A conductor moves on, and makes contact with a set of parallel rails at a speed of 60 cm/s. A resistor R of 10Ω is connected to the point ab. The conductor length in the field is 40cm. Determine the magnitude of the current running through R.

Current is flowing from A to B

What is the equation I would use to solve this question?
