A rectangular coil of 100 turns measures 40.0 cm by 20.0 cm. This coil is placed next to an electromagnet which is switched on, increasing the magnetic field through the coil from zero to 0.800 T in 50.0 ms. If the resistance of the coil is 2.0 ohms, what are the induced voltage and current in the coil?

Question 2

After a switch is thrown to remove the battery from a DC LR circuit, but the circuit is still left complete, the time constant represents
 a. the time rate of change of the current in the circuit.
  b. the time rate of change of the induced emf in the circuit.
  c. the magnitude of the ratio of the current to the time rate of change of the current.
  d. all of the above. e. only (a) and (b) above.
