19- chapter31-question1 A circular wire loop of radius 12 cm is immersed in a uniform magnetic field 0.5 T with its plane normal to the direction of the field. If the field magnitude then decreases at a constant rate of -0.01 T/s at what rate should r (in x 10-³ m/s) increase so that the induced emf (in mm/s) the loop is zero? Option1 Option2 Option3 Option4 Option5 1.2 6.1 22 31 2.4 a) Option2 b) Option3 Option5 d) Option1 e) Option4 Boş bırak
