The source of all magnetism is
A)tiny pieces of iron.
B)tiny domains of aligned atoms.
C)ferromagnetic materials.
D)moving electric charge.
E)none of these

Question

Quizplus · Accepted Answer

Magnetism is caused by moving electric charge, specifically the movement of electrons within atoms. Therefore, tiny domains of aligned atoms (choice B) and ferromagnetic materials (choice C) are both related to magnetism, but they are not the source of magnetism. Tiny pieces of iron (choice A) may exhibit magnetism due to their ferromagnetic properties, but they are not the source of magnetism. Choice E is incorrect as there is a source of magnetism.
