Question

Consider a circuit placed in a magnetic field as shown below.  The conductor at the right end of the circuit is freely-moving bar. The magnetic field is directed out of the paper and has a strength is 4.60 T.  The resistor has a resistance of 2.50 ?. The bar at the right end of the circuit is 0.400 m long and is moved toward the resistor at a speed of 9.30 m/s.  Find the induced electromotive force in volts (V).

Consider a circuit placed in a magnetic field as shown below. The conductor at the right end of the circuit is freely-moving bar. The magnetic field is directed out of the paper and has a strength is 4.60 T. The resistor has a resistance of 2.50 ?. The bar at the right end of the circuit is 0.400 m long and is moved toward the resistor at a speed of 9.30 m/s. Find the induced electromotive force in volts (V).

Explanation / Answer

induced emf = B L v = 4.6 * 0.4 * 9.3 = 17.112 volts
