When a bar magnet of magnetic moment m and moment of inertia I (about the center, perpendicular to the length) is cut into two equal pieces perpendicular to the length, what would be the period T' for each piece, if T is the period of oscillations of the original magnet about an axis through the midpoint, perpendicular to the length, in a magnetic field B?
Options
- AT' = T
- BT' = 2T
- CT' = T/2
- DT' = 2T/m
Correct answer
C. T' = T/2
Step-by-step solution
Correct Option is : (C)
T' = T/2
T' = T/2
