A bar magnet of magnetic moment M and moment of inertia I is freely suspended such that the magnetic axial line is in the direction of magnetic meridian. If the magnet is displaced by a very small angle (theta), the angular acceleration is (magnetic induction of earth's horizontal field= `B_(H)`)

A bar magnet of magnetic moment M and moment of inertial I is in the direction of magnetic meridian. If the magnet is displaced by a very small angle (theta) , the angular acceleration is (Magnetic induction of earth's horizontal field =B_(H) )

A short bar magnet of magnetic moment 2Am^(2) and moment of inertia 6xx10^(2)kgm^(2) is freely suspended such that the magetic axial line is in the direction of magnetic meridian. If the magnet is displaced by a very small angle (3^(0)) ,the angular acceleration is -x10^(-6)rad//sec^(2) (Magnetic induction of earth's horizontal field =4xx10^(-4)T ).
