MCQ
A magnetic field exerts no force on:
- AA magnet
- BAn unmagnetised iron bar
- CA moving charge
- ✓Stationary charge
✓
Answer
Correct option: D.
Stationary charge
Moving charge can develop magnetic field and also experience the magnetic field.
But stationary charge do no have the ability to develop or experience magnetic field from the other magnetic fields.
Because moving charge gives rise to current which is responsible for the magnetic effects.
