A metal conductor of length rotates vertically about one of its ends at angular velocity radians per second. If the horizontal component of the earth's magnetic field is , then the e.m.f developed between the two ends of the conductor is
Step 1. Given data:
Angular velocity = radians per second
Horizontal component of the earth's magnetic field =
Step 2. Formula used:
Step 3. Calculations:
Putting all given values, we get
Thus, the correct option is option B.
