A square coil (length of a side 5 cm) with 100 windings and total resistance 100 Ω, the surface of which is perpendicular to the uniform magnetic field (0,6 T). The coil with a constant speed of 0.1 s is extracted from the field (i.e. where B = 0 T). Calculate a) magnetic flux change; b) average induced voltage and current; c) thermal energy released into the coil; d) the force with which the coil was pulled from the field.
