The hypothesis concerning the cause of magnetism is _

A. atoms all moving in the same direction
B. electrons all moving in the same direction
C. magnetic line-up of atoms
D. all of the above

The hypothesis concerning the cause of magnetism is electrons all moving in the same direction .

Explanation:

Magnetism is triggered by the electric charges being transferred. Each substance consists of tiny units, called atoms. Some of the electrons spin in the same direction, in substances like cobalt, nickel, and iron. That makes the atoms highly magnetic in this compounds-but they are not magnets yet.Magnetism is a physical property generated by electric charge movement which results in attractive and repulsive forces between objects.
