Consider the two coplanar conductors (infinitely long wire and the conducting rectangular loop) with the given coordinate system. A current I is flowing on the long wire.
1) Find the induced voltage in the rectangular loop if the loop is stationary and the current I = I0 cos (wt ).
2) Repeat part (1) if the current is I0 and the loop moves away from the long wire with a velocity μ = ax μ0
3) Repeat part (1) if the current is I = I0 cos (wt ) , and the loop moves away from the long wire with a velocity μ = ax μ0
