1. A square loop of side 10 cm and resistance 1 Q is moved towards night with a constant velocity v shown in the figure. The left arm of the loop is in a uniform magnetic field of 2 T. The field is perpendicular to the plane of the drawing and is going into it. The loop is connected to a network of resistors each of value 30. With what speed should the loop be moved so that a P steady current of 1 mA flows in the loop. 30 3Ο X X x x X x x X x 30 30 x X Х x 2. A square: loop of edge a having n turns is rotated with a uniform angular velocity co about one of its diagonals which is kept fred in a horizontal position (figure 38-W6). A uniform magnetic field B exists in the vertical direction. Find the emf induced in the coil
