Teaching HTET PGT Level 3 - 2024 Mock Test Physics Moving Charges and Magnetism The Magnetic Dipole Moment
The time period of oscillations of a bar magnet when it is suspended in a uniform magnetic field ‘B’ is found to be 2 seconds. The same bar magnet is remagnetised so that its pole strength is 4 times the initial value. If it is suspended in the same magnetic field ‘B’ as in the earlier case, then its time period of oscillation will be:
