Answer #1

the magnitude of the induced emf is E = Blv

                                                              = 4 * 2.5 * 4

                                                              = 40 V

A 20 turn loop is immersed in a magnetic field that’s spatially uniform and varies in strength. Initially, the plane of the loop is perpendicular to the magnetic field. At t= 0 s, the loop starts to rotate so that 1.00 s later, the plane of the loop is parallel to the magnetic field, thus rotating so that it completes one rotation in 4.00 s. The magnetic field strength varies according to ?=1.20?^(−?1.90)T. The loop’s radius is 12.0 cm. What...
