Question: 

When a car drives through the Earth’s magnetic field, an emf is induced in its vertical 55-cm-long radio antenna. If the Earth’s field $(5.0 \times 10^{-5} \textrm{ T})$ points north with a dip angle of $38 ^\circ$, what is the maximum emf induced in the antenna and which direction(s) will the car be moving to produce this maximum value? The car’s speed is 30.0 m/s on a horizontal road.
