Two straight conducting rails form a right angle where their ands are joined. A conducting bar contanct with the rails starts at vertex at the time `t=0` & moves symmetrically with a constant velocity of `5.2 m//s` to the right as shown in figure. A `0.35 T` magnetic field point out of the page. Calculate:
(i) The flux through the tringle by the rails & ber at `t=3.0 s`.
(ii) The emf around the tringle at that time.

In what manner does the emf around the tringle vary with time.

Answer

`56.8 V;`
