Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Why does the attractive force between two magnets increase?
A
The like poles are pointed at each other and move farther apart.
B
The like poles are pointed at each other and move closer together.
C
The unlike poles are pointed at each other and move farther apart.
D
The unlike poles are pointed at each other and move closer together.
Explanation: 

Detailed explanation-1: -This is because magnetic forces depend on distance. The closer the two magnets are together, the stronger the force between them. So, as the distance decreases, the force increases, but the farther away they are, the weaker the magnetic force is. So, distance increases; force decreases.

Detailed explanation-2: -We figure out: The magnetic field around a magnet (and thus an electromagnet) gets stronger when it is closer to another magnet, which means that the force between two magnets will be stronger as the magnets get closer together.

Detailed explanation-3: -The new magnet may attract or repel the suspended magnet. When opposite poles of the magnets approach, they attract each other. Any north-south combination will pull them together.

Detailed explanation-4: -When you have more than one magnet, like (or same) poles repel, or push, each other. Opposite poles attract, or pull, each other.
