Question

A pickup truck has a width of 79.7 in. If it is traveling north at 39 m/s through a magnetic field with vertical component of 33 µT, what magnitude emf is induced between the driver and passenger sides of the truck?

A pickup truck has a width of 79.7 in. If it is traveling north at 39 m/s through a magnetic field with vertical component of 33 µT, what magnitude emf is induced between the driver and passenger sides of the truck?

Explanation / Answer

formula for induced emf e = v B L sin theta

where L is length

B is magnetic fied

theta = 90 deg

v is veocity

also 1 in = 0.0254 m

so

emf e = (79.7* 0.0254 * 39 *33 e -6)

emf e = 2.6 mV
