Time period of oscillation of a magnetic needle is

A magnet takes a minute to make 30 oscillations in a magnetic field. If the strength is doubled, then the time period of oscillation (in S) is

State the expression for the time period of angular oscillations of the bar magnet.

A bar magnet suspended freely has period of oscillation of 2s. Now, the bar magnet is broken into equal halves and one-half is suspended to oscillate freely in the same magnetic field. Find the time period of oscillation of this half of the magnet.

A bar magnet suspended freely has period of oscillation of 2s. Now, the bar magnet is broken into equal halves and one-half is suspended to oscillate freely in the same magnetic field. Find the time period of oscillation of this half of the magnet.

A magnetic needle made of iron is suspended in a uniform external magnetic field. It experiences a torque and the needle starts oscillating. Write down the frequency of oscillation of the magnetic needle.

(Attempt any ten of the following questions) A magnetic dipole is oscillating in a magnetic field obeying the following expression. d^2 theta/dt^2 = -mB/I theta What is the time period of oscillation and mention the nature of oscillation?
