A coil with an inductance of 2.0 H and a resistance of 10ohm is suddenly connected to an ideal battery with e= 100 V. At 0.10 s after the connection is made, what is the rate at which (a) energy is being stored in the magnetic field, (b) thermal energy is appearing in the resistance, and (c) energy is being delivered by the battery?
The magnetic field in the region between the poles of an electromagnet is uniform at any time, but is increasing at the rate of 0.060 T/s. The area of the conducting loop in the field is 120cm^2, and the total circuit resistance, including the meter, is 6.0. What is the magnitude of the inductee emf?
