Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]

Amy used a magnet to hold one piece of paper on the refrigerator. Later, she tried to use the same magnet to hold a stack of four pieces of paper, and the magnet wouldn’t stick to the fridge. Why did this happen?

A	The magnet needs glue
B	The magnet couldn’t hold due to the thickness of the paper
C	Paper repels magnets
D	A magnet isn’t attracted to the refrigerator.

Explanation:

Detailed explanation-1: -Amy used a magnet to hold one piece of paper on the refrigerator. Later, she tried to use the same magnet to hold a stack of four pieces of paper, and the magnet wouldn’t stick to the fridge. Why did this happen? A magnet isn’t attracted to the refrigerator.

Detailed explanation-2: -This happens because the magnetic force can work from a distance and physical contact is not necessary to achieve the magnetic force.

Detailed explanation-3: -Summary. The magnetic force of the fridge magnet is the force that keeps this magnet ‘stuck’ to the fridge door. In our example, magnetic force is stronger than all other forces affecting the fridge magnet.

Detailed explanation-4: -The magnetic strip is used to line the door of the refrigerator. It helps to keep the door shut.

Detailed explanation-5: -Similarly, refrigerator magnets are made of a material that is permanently magnetized – they don’t use an electric current to generate a magnetic field.
