← A rod 0.29 m long slides at 6.5 m/s along rails in a field of 0.37 T. The circuit has a resistance of 0.55 Ω. How much power must be supplied to keep the speed steady?A magnet is pushed into a closed coil in 0.22 s, and a charge of 4.6 mC flows round the circuit. The same magnet is pushed in the same way, but in 0.11 s. How much charge flows now? →
