4. A coil with 20 turns of wire is wrapped on a frame with a square cross section 2.50 cm on a side. Each turn has the same area, equal to that of the frame, and the total resistance of the coil is 0.500 2. An applied uniform magnetic field is perpendicular to the plane of the coil, going up as in Figure. (a) If the field changes uniformly from 0.00 T to 0.500 T in B 0.500 s, what is the induced emf in the coil while the field is changing? (b) Find the magnitude and the direction of the induced current in the coil while the field is changing. Please explain your findings in details.

Consider the system pictured in Figure P28.26. A 15.0-cm horizontal wire of mass 15.0 g is placed between two thin, vertical conductors, and a uniform magnetic field acts perpendicular to the page. The wire is free to move vertically without friction on the two vertical conductors. When a 5.00-A current is directed as shown in the figure, the horizontal wire moves upward at constant velocity in the presence of gravity. (a) What forces act on the horizontal wire, and (b) under what condition is the wire able to move upward at constant velocity? (c) Find the magnitude and direction of the minimum magnetic Field required to move the wire at constant speed. (d) What happens if the magnetic field exceeds this minimum value? Figure P28.26
