Question

What happens when the N-pole of a magnet is brought near the N-pole of a suspended magnet?
A. It attracts the suspended magnet
B. It pushes the suspended magnet away
C. It makes the suspended magnet rotate
D. It doesn't effect the suspended magnet in any way

Answer 1

Hint:A magnet is an entity or substance that generates a magnetic field. It has a north and south pole, and opposite poles attract each other while like poles repel each other. Magnets are ferromagnetic materials made up of various atoms and molecules.

Complete answer:
Temporary, permanent, and electromagnets are the three kinds of magnets. Due to the presence of magnetic fields, temporary magnets become magnetised. Permanent magnets may be chemical compounds or naturally occurring elements. Running an electrical current into a coil with a metal core produces electromagnets.

A. It attracts the suspended magnet: The magnet does not attract the suspended magnet as poles repel each other. Hence this is not the correct option.

B. It pushes the suspended magnet away: Magnetism can operate over distances, and magnets can exert force (push or pull) on surfaces even though they are not in contact with them. When a magnet's north pole is brought next to the north pole of a suspended magnet, the suspended magnet is pushed away by it. Hence this is the correct option.

C. It makes the suspended magnet rotate: The magnet does not rotate the suspended magnet as like poles repel each other. Hence this is not the correct option.

D. It doesn't affect the suspended magnet in any way: The magnet does affect the suspended magnet by pushing it away. Hence this is not the correct option.

Therefore, the correct option is B.

Note:Refrigerator and freezer doors are sealed with magnets to ensure a secure seal. Magnets are used to store data in computers and are crucial in scanning devices such as MRIs (magnetic resonance imagers), which surgeons use to examine people's bodies.
