Which of these objects would be attracted to a magnet?
- A.
A steel key
- B.
A leather purse
- C.
A wooden ruler
Correct Answer
A. A steel keyExplanation
A steel key would be attracted to a magnet because steel is a ferromagnetic material, which means it contains iron and can be magnetized. When a magnet is brought close to a steel key, the magnetic field of the magnet causes the magnetic domains within the steel to align, creating a temporary magnetic field in the key. This attraction occurs because opposite magnetic poles attract each other.Rate this question:

Magnet A can hold three steel paperclips. Magnet B can hold five. Which is the strongest?
- A.
Magnet B
- B.
Magnet A
- C.
They are both equally strong
Correct Answer
A. Magnet BExplanation
Magnet B is the strongest because it can hold five steel paperclips, while Magnet A can only hold three. The strength of a magnet is determined by its ability to attract and hold magnetic materials, and in this case, Magnet B has a greater capacity to hold paperclips than Magnet A. Therefore, Magnet B is stronger.Rate this question:

Two magnets are placed next to each other and push (repel) each other apart. What is one possible explanation for this?
- A.
The north pole of one magnet is facing the south pole of the other magnet
- B.
One magnet is made of gold
- C.
The north poles of both magnets are facing one another
Correct Answer
C. The north poles of both magnets are facing one anotherExplanation
When two magnets are placed next to each other and push each other apart, one possible explanation for this is that the north poles of both magnets are facing one another. Like poles of magnets repel each other, so when the north poles of both magnets are facing each other, they exert a repulsive force that causes them to push apart.Rate this question:

The pushing or pulling force of a magnet is?
- A.
Strongest in the middle of the magnet
- B.
Strongest at the ends of the magnet
- C.
The same all the way through the magnet
Correct Answer
B. Strongest at the ends of the magnetExplanation
The correct answer is strongest at the ends of the magnet. This is because the magnetic field lines of a magnet are strongest at the poles, which are located at the ends of the magnet. The magnetic force exerted by a magnet is strongest at its poles, making the pushing or pulling force strongest at the ends of the magnet.Rate this question:

Which two metals will be attracted by a magnet?
- A.
Iron and steel
- B.
Gold and silver
- C.
Aluminium and lead
Correct Answer
A. Iron and steelExplanation
Iron and steel are attracted by a magnet because they are ferromagnetic materials. Ferromagnetic materials have magnetic domains that align in the presence of a magnetic field, creating a net magnetic moment. This alignment allows the magnet to attract and hold onto the iron and steel objects. Gold, silver, aluminium, and lead are not attracted to a magnet because they are non-magnetic or have very weak magnetic properties.Rate this question:

When two magnets repel each other, they ...
- A.
Push away from each other
- B.
Pull towards each other
- C.
Neither push nor pull
Correct Answer
A. Push away from each otherExplanation
When two magnets repel each other, it means that they exert a force on each other that causes them to move away from each other. This is due to the interaction between the magnetic fields of the magnets. The like poles of the magnets (either both north or both south) repel each other, resulting in a pushing force. Therefore, the correct answer is "push away from each other".Rate this question:

When two magnets attract each other, they ...
- A.
Push away from each other
- B.
Pull towards each other
- C.
Neither push nor pull
Correct Answer
B. Pull towards each otherExplanation
When two magnets attract each other, they pull towards each other. This is because magnets have two poles, a north pole and a south pole. Opposite poles attract each other, so the north pole of one magnet will attract the south pole of another magnet. This attraction causes the magnets to pull towards each other.Rate this question:

Magnetism is a type of ...
- A.
Electricity
- B.
Gravity
- C.
Force
Correct Answer
C. ForceExplanation
Magnetism is a type of force. It is the force exerted by magnets or magnetic fields on other magnets, magnetic materials, or moving charged particles. It is not a type of electricity or gravity, although it can interact with electric currents and is influenced by gravitational forces.Rate this question:
