Magnetic moment for a solenoid and corresponding bar magnet is
1 equal for both
2 more for solenoid
3 more for bar magnet
4 none of these
Explanation:
A We know that, solenoid and corresponding bar magnet produces same magnetic fields here the magnetic for both will be equal. Hence, magnetic moment for a solenoid and corresponding bar magnet is equal for both.
