A circular coil of 16 turns and radius 10cm carries a current of \[0.75\text{ }A\] and rest with its plane normal to an external magnetic field of \[5.0\times {{10}^{-2}}T.\] The coil is free to rotate about its stable equilibrium position with a frequency of \[2.0\text{ }{{s}^{-1}}\]. Compute the moment of inertia (in \[kg{{m}^{2}}\]) of the coil about its axis of rotation.
