Two fixed long parallel horizontal rails...

Two fixed long parallel horizontal rails, a distance 1 m apart are joined at one end by a resistance `1Omega`. A rod AB of negligible resistance slides towards the resistance. A magnetic field of magnitude 4T perpendicular to the plane of rails exists. Find the current flowing (in Ampere) in the resistance, at an instant when the velocity of the rod is 2 m/s.

Text Solution

Verified by Experts

The correct Answer is:
8
EMF induced `=BLV=4xx2xx1=8V`
Current produced `=(BLV)/( R )=(8)/(1)=8A`
