The time period of a freely suspended magnetic needle does not depend upon

Question

The time period of a freely suspended magnetic needle does not depend upon (A) length of the magnet (B) pole strength (C) horizontal component of earth's magnetic field (D) length of the suspension fibre

Tardigrade Admin · Accepted Answer

The time period of oscillation of a bar magnet suspended in air is given by

T = 2 π \frac{I}{M B _{H}}

It depends on , Moment of Inertia( depends on length and breadth of the magnet), magnetic moment and earth's horizontal magnetic field.

Q. The time period of a freely suspended magnetic needle does not depend upon

length of the magnet

pole strength

horizontal component of earth's magnetic field

length of the suspension fibre

The time period of oscillation of a bar magnet suspended in air is given by T=2πMBH​I​​ It depends on , Moment of Inertia( depends on length and breadth of the magnet), magnetic moment and earth's horizontal magnetic field.
