A small magnetic needle is set into oscillations in a magnetic field B obtain an expression for the time period of oscillation.

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

Time period of oscillation of a magnetic needle is

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.

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

A magnetic needle oscillates in a uniform magnetic field of strength B1, with a time period of 10 seconds. The same magnetic needle oscillates in another uniform magnetic field of strength B 2 with a time period 20 seconds. Which magnetic field is strong, B1, or B2,? Why?
