Suppose a long rectangular loop o width ww is moving along the xx-direction with its left arm in magnetic field perpendicular to the plane of the loop (see figure). The resistance of the loop is zero and it has an inductance L.L . At time, t=0,t = 0, its left arm passes the origin, O.O .

Suppose a long rectangular loop o width w is moving along the x -direction with its left arm in magnetic field

If for t≥0,t \ge 0, the current in the loop is II and the distance of its left arm from the origin is x,x, then II versus xx garph will be

Step-by-step solution

Suppose a long rectangular loop o width w is moving along the x -direction with its left arm in magnetic field

VBℓ−Ldidt=0VBℓ - L\dfrac{di}{dt} = 0

VBℓ=LdidtVBℓ = L\dfrac{di}{dt}

⇒didt=VBℓL⇒ \dfrac{di}{dt} = \dfrac{VBℓ}{L}

=+ve= + ve slope

x=ut⇒dxdt=Vx = ut ⇒ \dfrac{dx}{dt} = V

didx=BℓL=+ve\dfrac{di}{dx} = \dfrac{Bℓ}{L} = + ve slope
