A right angled triangle abc, made from a metallic wire, moves at a uniform speed v in its plane as shown in . A uniform magnetic field B exists in the perpendicular direction. Find the emf induced (a) in the loop abc, (b) in the segment bc, (c ) in the segment ac and (d) in the segment ab.

Explanation

(a) Since entire loop is in magnetic field, no change in flux hence emf in loop `abc` is zero

(c)
: on induced emf because `v || vec(l)`
(d)
`eB(vsintheta)((l)/(sintheta))` or Since net emf in the loop is zero, no emf in `ac` , therefore emf in `bc` should be equal and opposite to `bc`
