A uniform rectangular coil of total mass 210 g and dimensions 0.500 m X 1.00 m is oriented perpendicular to a uniform 3.00-T magnetic field (Fig). A current of 2.00 A is suddenly started in the coil.(a) About which axis (A, or A2) will the coil begin to rotate? Why?(b) Find the initial angular acceleration of the coil just after the current is started. You are watching: Find the initial angular acceleration of the coil just after the current is started.
