Experiment about emf.

  1. Jan 24, 2014 #1
    The attached drawing represents 4 wires. The top and down are still. The right and left move with the same velocity v as shown by the arrows.

    There is a magnetic field perpendicular to the page.

    Will there be a current flowing through the circuit formed by the 4 wires?

    Yes. Each will get an EMF in the opposite direction, leading to a current loop.

    Another way of looking at it is that the area of the circuit is shrinking, and so, therefore, is the magnetic flux, B.A, linking the circuit.
