Question

When a car drives through the Earth’s magnetic field, an emf is induced in its vertical 60-cm-long radio antenna. Part A If the Earth’s field (5.0×10−5 T) points north with a dip angle of 38∘, which direction(s) will the car be moving to produce the maximum emf induced in the antenna?

    Answer:

    Explanation:

    The magnetic field is in north south direction . In order to cut lines of forces to the maximum extent  , car has to move in east- west direction ie towards east or towards west to produce maximum emf.

    emf produced = B L V

    where B is horizontal component of earth magnetic field

    L is length of rod

    v is velocity of car carrying antenna rod .
