Question

A magnet can hold a piece of paper to the door of a refrigerator. How does the magnet stick without touching the door?

Atoms from the magnet pass through the paper and touch the door.

Gravity attracts the magnet to the door.

The magnetic force of the magnet can act at a distance.

The magnet induces a magnetic field in the paper.

Answer 1

Answer:

The magnetic force of the magnet can act ar a distance is the correct answer..

Hope it helps.

thank u

Answer 2

The magnet sticks without touching the door because the magnetic force of the magnet can act at a distance.

• The fridge door is made out of ferromagnetic metal which can easily attach a magnet on it's surface.

• Now,if we attach a paper between the contact surface of the magnet and the metallic fridge surface,the magnet still gets attached to the fridge with the inbetween paper.

• This happens because the magnetic force can work from a distance and physical contact is not necessary to achieve the magnetic force.
