Because magnetic monopoles are not observed, what is used to explain all magnetic effects?
ANeutrons
BPhotons
CCurrents
DMonopoles
Answer & Solution
Correct answer: C. Currents
1. Magnetism must be traced back to something that does exist.
2. Isolated north and south magnetic poles are called magnetic monopoles.
3. Since magnetic monopoles are not observed, another explanation is needed.
4. Currents are used to explain all magnetic effects.
