Question
The Figure shows a metal bar sliding at 1.5 cm/s over a U-shaped metal rail. At t=0, the external
magnetic field is 0.2 T out of the page, and is increasing at the rate of 0.1 T/s. Take l = 5.0 cm, and at t=0,
x = 5.0 cm. Find the induced emf.
Hint: The induced emf is produced both by the motion of the bar and by the changing external magnetic
field.
