Question
As the lesson discussed, electromotive force (in volts) is generated by a change in flux. This induced voltage,
, is given by the formula,
in wire loops where current can flow. Remember, flux is the product of magnetic field and area:
In this picture below, the magnetic field is pointing out of the page. The "loop" is on the right. As the bar moves to the left, the flux
of the loop because the area of the loop increases. Current is induced to oppose this change in flux, generating an induced magnetic field that . Therefore, the current will
