Question

The period of oscillation of a bar magnet in a vibration magnetometer is 2 sec. The period (in sec) of oscillation of a bar magnet whose magnetic moment is 4 times that of 1st magnet is - (A)  (B)  (C)  (D)

Tardigrade Admin · Accepted Answer

( T 2/ T 1)=√( M 1/ M 2)=√( M 1/4 M 1) T 2=(2/2)=1 sec

Q. The period of oscillation of a bar magnet in a vibration magnetometer is $2 sec$ . The period (in $sec$ ) of oscillation of a bar magnet whose magnetic moment is $4$ times that of $1$ st magnet is -

$\frac{T _{2}}{T _{1}} = \frac{M _{1}}{M _{2}} = \frac{M _{1}}{4 M _{1}}$
$T_{2} = \frac{2}{2} = 1 sec$
