The hypothesis concerning the cause of magnetism is electrons all moving in the same direction
.
<u>Explanation</u>:
- 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.
Answer:
