Question

A square coil of wire of side 2.75 cm is placed in a uniform magnetic field of magnitude 1.50 T directed into the page as in the figure shown below. The coil has 24.5 turns and a resistance of 0.780 Ω. If the coil is rotated through an angle of 90.0° about the horizontal axis shown in 0.335 s, find the following. A square coil is shown in the plane of the page, and inside the coil a magnetic field points into the page. A horizontal rotation axis passes through the middle of the square. An arrow indicates that the square rotates clockwise on the axis when viewed from the left. (a) the magnitude of the average emf induced in the coil during this rotation mV (b) the average current induced in the coil during this rotation mA
