Question
A metal conductor of length 1 m rotates vertically about one of its ends at angular velocity 5 radians per second. If the horizontal component of earth’s magnetic field is 0.3 × 10−4 T, then the e.m.f. developed between the two ends of the conductor is
-
depends on the nature of the metal used
-
depends on the intensity of the radiation
-
depends both on the intensity of the radiation and the metal used
-
is the same for all metals and independent of the intensity of the radiation.
Solution
B.
depends on the intensity of the radiation
The emf induced between ends of conductor
