A 0.80 m long metal rod slides on two parallel rails in a uniform magnetic field of flux density 0.50 T directed into the page. The rails are connected by a 2.0 Ω resistor, forming a complete circuit. The rod is pulled to the right at 4.0 m s⁻¹. What is the current in the circuit?
- 0.80 A
- 0.40 A
- 1.6 A
- 3.2 A
