Test Preparation on Electromagnetic Induction-II-Physics Test Series For NEET 2020

A 10 metre wire kept in east-west direction is falling with
velocity 5 m/sec perpendicular to the field 0.3×10–4 Wb/m2.
The induced e.m.f. across the terminal will be-

A metal conductor of length 1m rotates vertically about one
of its ends at angular velocity 5 radians per second. If the
horizontal component of earth's magnetic field is 0.2×10–4 T,
then the e.m.f. developed between the two ends of the
conductor is-

A boat is moving due east in a region where the earth's
magnetic field is 5x10^-5 NA⁻¹ m⁻¹ due north and
horizontal. The boat carries a vertical aerial 2m long. If the
speed of the boat is  1.50  ms−1 , the magnitude of the
induced emf in the wire of aerial is-
