Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Two bar magnets are held close together. When they are released, they move toward one another. Which best describes the original placement of the magnets?
A
The magnets are placed end to end with the north pole of each pointing toward the other.
B
The magnets are placed end to end with the south pole of each pointing toward the other.
C
The magnets are placed side by side with the like poles of each magnet near the other.
D
The magnets are placed side by side with the opposite poles of each magnet near the other.
Explanation: 

Detailed explanation-1: -Two bar magnets are held close together. When they are released, they move toward one another. Which best describes the original placement of the magnets? The magnets are placed end to end with the north pole of each pointing toward the other.

Detailed explanation-2: -If we try to place two equal-sized magnet bars one above the other such that their north poles are on the same side, they will repel each other, it is because like poles of two magnets repel each other.

Detailed explanation-3: -When two magnets are brought close together, their magnetic fields interact. You can see how they interact in the Figure below. The lines of force of north and south poles attract each other whereas those of two north poles repel each other.

Detailed explanation-4: -When opposite poles of the magnets approach, they attract each other. Any north-south combination will pull them together. But when two like poles come together, they push each other apart. Two north poles will not stick together.

Detailed explanation-5: -Bar magnets should be stored in pairs always, with their unlike poles on the same side separated by a piece of non-magnetic material like wood and covered by magnetic materials, like soft iron at the edges/poles in the following manner.
