A rectangular current-carrying loop with dimensions 4.0 cm × 6.0 cm carries a current of 2.5 A and is placed in a uniform magnetic field of 0.80 T. The magnetic field makes an angle of 30° with the normal to the loop's plane. If the loop is free to rotate about an axis perpendicular to the magnetic field, what is the maximum kinetic energy the loop can achieve if released from rest at the initial position?
