Atechnician is working on an mri machine. to test it, the technician turns on the mri machine that produces a strong magnetic field, but then he accidentally drops a screwdriver in this magnetic field. as the screwdriver falls, an emf is induced across the length of the metal shaft, l, of the screwdriver. at one instant, the screwdriver falls with a speed of 2.1 m/s and is oriented as shown in figure so that the induced emf is maximized. the magnitude of the magnetic field at this instant is 2.5 t, and the length of the metal shaft, l, is 10 cm. what is the induced emf across the length of the metal shank at this instant?
