# Current carrying coil placed in a magnetic field

A uniform rectangular coil of total mass 270 g and dimensions 0.5m x 1.0m is oriented perpendicular to a uniform 3.90-T magnetic field (the figure). A current of 2.30 A is suddenly started in the coil.

Find the initial angular acceleration of the coil just after the current is started (rad/s^2).

See document attached for figure.
