The effect due to uniform magnetic field on a freely suspended magnetic needle is as follows :
- A both torque and net force are present
- B torque is present but no net force
- C both torque and net force are absent
- D net force is present but not torque
Answer & Solution
Correct Answer
(B) torque is present but no net force
Step-by-step Solution
Detailed explanation
When a magnetic needle is placed in a uniform magnetic field, equal and opposite forces act on the poles of the needle which give rise to a torque, but not net force.
