Ampere's hypothesis explains all magnetic phenomena through:
AIsolated magnetic charges
BStatic electric fields
CCirculating currents
DGravitational effects
Answer & Solution
Correct answer: C. Circulating currents
Ampere proposed that magnetism arises from circulating currents, so a bar magnet is like a solenoid.
