Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Magnetism is ____
A
The part of the magnet where the force is the strongest
B
A force created by magnets that pulls some metals
C
To Pull towards
D
An object able to pull some metals towards itself
Explanation: 

Detailed explanation-1: -A magnet is a rock or a piece of metal that can pull certain types of metal toward itself. The force of magnets, called magnetism, is a basic force of nature, like electricity and gravity. Magnetism works over a distance. This means that a magnet does not have to be touching an object to pull it.

Detailed explanation-2: -Magnetism is the force exerted by magnets when they attract or repel each other. Magnetism is caused by the motion of electric charges.

Detailed explanation-3: -Answer and Explanation: The magnetic force is not just one type of force pull or push. Magnetism is a physical phenomenon with fields that attract (pull) metals or magnets and repel (push) other magnets.

Detailed explanation-4: -The force that a magnet exerts is called magnetic force. The force is exerted over a distance and includes forces of attraction and repulsion.

Detailed explanation-5: -This is because magnets attract materials that have unpaired electrons that spin in the same direction. In other words, the quality that turns a metal into a magnet also attracts the metal to magnets. Many other elements are diamagnetic-their unpaired atoms create a field that weakly repels a magnet.
