A metallic block carrying current `I` is subjected to a uniform magnetic induction `vec(B) as shown in Figure . The moving charges experience a force ` vec(F) given by ….. Which results in the lowering of the potential of the face ……. Assume the speed of the carries to be `v` .
Text Solution
Verified by Experts
The correct Answer is:
A, B, C, D
` vec (F) = q(vec(v)xxvec(B)) = (-e) (-v hat (i)xx B hat(j)) = ev Bhat(k)`
