Problem 6: A single circular loop with a radius of R=50 cm is placed in a uniform external magnetic field with initial strength of 30 T so that the plane of the coil is perpendicular to the field. The strength of the B-field changes to-10 T in 0.2 sec. The loop includes resistor of resistance of 250 n. a) Find the average induced emf(AV) during this time interval of 0.3 sec. b) What's the induced current I and power P dissipated through the resistor R? c) What is the magnitude of the induced magnetic field (produced by this induced current) along this circular loop/wire? d) What would the average induced emf and the induced current be if there were 15 loops?
