    What do you need to make an electromagnet?

    • Metal

    • Iron

    • Biaron

    • Silver

    Correct Answer
    A. Iron
    Explanation
    To make an electromagnet, you need iron. Iron is a ferromagnetic material, which means it can be easily magnetized. When an electric current passes through a coil of wire wrapped around the iron core, it creates a magnetic field, turning the iron into a magnet. This allows the electromagnet to attract and repel other magnetic objects.

    Rate this question:

  • 3. 

    ___________ - is an attraction of magnet for another object.

    • Electron

    • Steel

    • Domain

    • Magnetism

    Correct Answer
    A. Magnetism
    Explanation
    Magnetism is the attraction of a magnet for another object. It is a force that causes certain materials, such as iron or steel, to be attracted to magnets. Magnetism is caused by the alignment of electrons in the material, creating a magnetic field. This magnetic field then interacts with the magnetic field of the magnet, resulting in the attraction between the two objects.

    Rate this question:

  • 4. 

    ____________ - is force around a magnet.

    • Friction

    • Radiation

    • Magnetic field

    • Magnetism

    Correct Answer
    A. Magnetic field
    Explanation
    A magnetic field is the force around a magnet. It is the area in which a magnetic force can be detected and is created by the movement of electric charges. This force can attract or repel other magnets or magnetic materials. Magnetic fields play a crucial role in various applications, such as generating electricity in power plants, operating electric motors, and guiding compass needles.

  • 5. 

    Is a pernament made out of a magnetic field?

    • True

    • False

    Correct Answer
    A. False
    Explanation
    A permanent magnet is made out of a material that can retain its magnetism over a long period of time. It is not made out of a magnetic field itself. The magnetic field is created by the alignment of the magnetic domains within the material. Therefore, the statement that a permanent magnet is made out of a magnetic field is incorrect.

    Rate this question:

  • 6. 

    Earth's magnetic fields are __________ at poles.

    Correct Answer
    strongest, STRONGEST
    Explanation
    Earth's magnetic fields are strongest at the poles because the magnetic field lines converge at the poles, creating a concentrated and intense magnetic field. This is due to the Earth's magnetic field being generated by the movement of molten iron in its outer core. As the molten iron circulates, it creates electric currents that generate the magnetic field. The convergence of field lines at the poles results in a stronger magnetic field compared to other regions on Earth.

  • 7. 

    Check at least two ways to increase the strength of an electromagnet.

    • Make loops tighter

    • Use metal

    • Increase friction

    • Use iron

    Correct Answer(s)
    A. Make loops tighter
    A. Use iron
    Explanation
    Making the loops tighter in an electromagnet increases its strength because it increases the number of turns in the coil, which in turn increases the magnetic field produced. Using iron also increases the strength of an electromagnet because iron is a ferromagnetic material that enhances the magnetic field.

    Rate this question:

  • 8. 

    A magnetic ________ is when all magnetic fields are lined up in the SAME way.

    Correct Answer(s)
    domain, DOMAIN
    Explanation
    A magnetic domain is a region within a material where the magnetic fields of atoms or molecules are aligned in the same direction. This alignment creates a stronger overall magnetic field within the domain. When all the magnetic fields in a material are lined up in the same way, it is referred to as a magnetic domain. The correct answer is "domain, DOMAIN" because it accurately describes the concept of aligned magnetic fields within a material.

    Rate this question:

  • 9. 

    What is an electromagnet? Check one box.

    • A magnet made of iron

    • Electricity

    • A core strong temporary magnet

    • Poles

    Correct Answer
    A. A core strong temporary magnet
    Explanation
    An electromagnet is a temporary magnet that is created by passing an electric current through a coil of wire. The coil of wire, also known as the core, becomes magnetized when the electric current flows through it, creating a magnetic field. This magnetic field can attract or repel other magnets or magnetic materials. Unlike a permanent magnet, an electromagnet only exhibits magnetic properties when the electric current is flowing through it.
