30. Induction and Inductance
Motional EMF
5PRACTICE PROBLEM
Consider a 25-cm-long zero-resistance metal rod that moves on frictionless, zero-resistance parallel rails at a constant speed of 12 m/s within a 0.15 T uniform magnetic field, as shown below. The rails are connected by a conducting path that has a resistance of 1.5Ω. Determine the induced current in the circuit.
