Physics Quiz: Theory Practice Questions On Magnetism! - Quiz

In the scientific study of physics, magnetism is a class of phenomena which are mediated by magnetic fields. What can you tell us about this particular realm of science? Let’s take a look right now.

Questions and Answers
  • 1. 

    Define magnet

    • A.

      A group of atoms with the magnetic fields lined up in the same direction

    • B.

      A material that attracts other magnets

    Correct Answer
    B. A material that attracts other magnets
    Explanation
    A magnet is defined as a material that attracts other magnets. This means that when a magnet is brought close to another magnet, they will exert a force on each other and come together. This property is due to the presence of magnetic fields within the material, which align in a specific direction and create a magnetic force. Therefore, a magnet can be identified as a substance that has the ability to attract and interact with other magnets.

    What are the two type of magnets

    • A.

      Alternating and direct

    • B.

      Strong and weak

    Correct Answer
    B. Strong and weak
    Explanation
    The correct answer is "strong and weak". This is because magnets can be classified based on their strength, which refers to their magnetic field intensity. Some magnets have a strong magnetic field and are capable of exerting a greater force on other magnetic materials, while others have a weak magnetic field and exert a lesser force. Therefore, "strong and weak" accurately describes the two types of magnets based on their magnetic field strength.

    Like magnetic poles

    • A.

      Repel

    • B.

      Attract

    Correct Answer
    A. Repel
    Explanation
    Like magnetic poles repel each other because they have the same type of magnetic field. This means that if two magnets have their north poles facing each other, they will push away from each other. On the other hand, opposite magnetic poles attract each other. So, if a north pole and a south pole of two magnets are facing each other, they will be pulled towards each other.

    Describe a magnetic field

    • A.

      A material that attracts other magnets and causes the force that attracts or repels a magnet

    • B.

      Surrounds a magnet pointing from north pole to south pole and causes the force that attracts or repels a magnet

    Correct Answer
    B. Surrounds a magnet pointing from north pole to south pole and causes the force that attracts or repels a magnet
    Explanation
    A magnetic field is a region in space that surrounds a magnet and is characterized by the direction of the force it exerts on other magnets. It points from the north pole to the south pole of the magnet and is responsible for the attraction or repulsion between magnets.

  • 5. 

    Every magnetic field has poles: true or false

    • A.

      True

    • B.

      False

    Correct Answer
    A. True
    Explanation
    Every magnetic field does indeed have poles. The poles of a magnet are the points where the magnetic field is strongest and where the magnetic force is concentrated. These poles are referred to as the north and south poles. Magnetic fields are created by the movement of electric charges, such as the flow of electrons in a wire or the spinning of electrons in an atom. These moving charges create a magnetic field that has distinct north and south poles. Therefore, it is true that every magnetic field has poles.

    An atom is:

    • A.

      The smallest magnet

    • B.

      A magnetic field

    • C.

      A magnetic domain

    Correct Answer
    A. The smallest magnet
    Explanation
    An atom can be considered as the smallest magnet because it consists of charged particles, such as protons and electrons, which create a magnetic field. The movement of these charged particles within an atom generates a magnetic field, similar to how a magnet produces a magnetic field. Therefore, an atom can exhibit magnetic properties and be regarded as the smallest magnet.

    A  magnetic domain :

    • A.

      Requires a group of atoms with the magnetic fields lined up in the same direction

    • B.

      Requires only a weak magnetic field to get domains to line up in the same direciton

    Correct Answer
    A. Requires a group of atoms with the magnetic fields lined up in the same direction
    Explanation
    A magnetic domain refers to a region within a material where the magnetic fields of the atoms are aligned in the same direction. This alignment is necessary for the material to exhibit magnetic properties. The answer correctly states that a magnetic domain requires a group of atoms with their magnetic fields lined up in the same direction, indicating that the alignment of magnetic fields is essential for the formation of magnetic domains.

    Strong magnetic material :

    • A.

      Is a group of atoms with the magnetic fields lined up in the same direction

    • B.

      Requires only a weak magnetic field to get domains to line up in the same direciton

    Correct Answer
    B. Requires only a weak magnetic field to get domains to line up in the same direciton
    Explanation
    The correct answer is "requires only a weak magnetic field to get domains to line up in the same direction." This is because strong magnetic materials have their atoms' magnetic fields aligned in the same direction. This alignment occurs when the material is exposed to a weak magnetic field, causing the domains (groups of atoms) to align. Therefore, only a weak magnetic field is needed to achieve this alignment in strong magnetic materials.

    Earth is a magnet and has a magnetic field: true or false

    • A.

      True

    • B.

      False

    Correct Answer
    A. True
    Explanation
    Earth is indeed a magnet and has a magnetic field. This is due to the movement of molten iron in its outer core, which generates electric currents and creates a magnetic field. This magnetic field extends from the Earth's interior to space, forming a protective shield around the planet. It plays a crucial role in protecting the Earth from harmful solar radiation and also aids in navigation for many species, including migratory birds and sea turtles.

    What causes earth magnetic field

    • A.

      Requires only a weak magnetic field to get domains to line up in the same direciton

    • B.

      A group of atoms with the magnetic fields lined up in the same direction

    • C.

      The motion of magma near the earths core

    Correct Answer
    C. The motion of magma near the earths core
    Explanation
    The motion of magma near the earth's core is the correct answer. The earth's magnetic field is generated by the movement of molten iron and nickel in the outer core of the earth. As the liquid metal moves, it creates electric currents, which in turn generate a magnetic field. This motion of magma is driven by the heat from the earth's core and the rotation of the planet.

  • 11. 

    How often does the earths magnetic field change directions 

    • A.

      Every four to five thousand years

    • B.

      Every eight to ten years

    • C.

      Every four to five million years

    Correct Answer
    A. Every four to five thousand years
    Explanation
    The Earth's magnetic field changes directions every four to five thousand years. This phenomenon is known as geomagnetic reversal or magnetic flip. It occurs when the magnetic poles of the Earth switch places, causing the magnetic field to reverse its direction. This process is gradual and can take thousands of years to complete. Scientists study these magnetic reversals to gain insights into the Earth's geological history and understand the behavior of the planet's magnetic field.

    The earths magnetic field

    • A.

      Deflects charged particles from the sun and is used to determine direction by humans and animals

    • B.

      Requires only a weak magnetic field to get domains to line up in the same direciton

    • C.

      Is a group of atoms with the magnetic fields lined up in the same direction

    Correct Answer
    A. Deflects charged particles from the sun and is used to determine direction by humans and animals
    Explanation
    The correct answer is that the Earth's magnetic field deflects charged particles from the sun and is used to determine direction by humans and animals. This is because the Earth's magnetic field acts as a shield, deflecting charged particles such as solar wind and cosmic rays away from the planet's surface. Additionally, many animals, such as birds and sea turtles, use the Earth's magnetic field as a navigational tool to determine direction during migration or foraging. Humans also rely on the Earth's magnetic field for navigation, as it helps in determining directions using compasses.

    What is used to increase or decrease the voltage in ac system

    • A.

      Transformers

    • B.

      Voltmeter

    Correct Answer
    A. Transformers
    Explanation
    Transformers are used to increase or decrease the voltage in an AC system. They work on the principle of electromagnetic induction, where an alternating current in the primary coil creates a changing magnetic field, which induces a voltage in the secondary coil. By varying the number of turns in the primary and secondary coils, transformers can step up or step down the voltage levels as required. This makes them essential for transmitting electricity over long distances, as high voltage is more efficient for transmission, and for adapting the voltage levels for different devices and appliances.
