A metallic rod held horizontally along east-west direction is allowed to fall vertically. Will an emf be induced in the rod?

A vertically metallic pole falls down through the plane of magnetic meridian. Will any emf be induced between its two ends?

A circular coil of radius 8 cm and 20 turns is rotated about it vertical diamter with an angular speed of 50 rad/s in a uniform horizontal magnetic field of 3.0 xx 10^-2 T. Calculate the maximum and average value of emf induced in the coil.
