A rod of mass m and length ℓ is being pulled with a constant velocity v on frictionless rails as shown. The initial distance of the rod from the end of the loop is ℓ0. The resistance of loop is R and it's self inductance is negligible. Magnetic field is present in space in vertically upward direction. Initially magnetic field is B0 and it starts decreasing at a constant rate till it becomes zero. m = 2kg. Take R = 5Ω, α = 0.1 T/sec, B0 = 2T, ℓ = ℓ m, ℓ0 = 1m, v = 5 m/s.

A rod of mass m and length ℓ is being pulled with a constant velocity v on frictionless rails as shown. The initial distance of the rod from the end of the loop is ℓ₀. The resistance of loop is R and it's self inductance is negligible. Magnetic field is present in space in vertically upward direction. Initially magnetic field is B₀ and it starts decreasing at a constant rate $\frac{dB}{dt} = α$ till it becomes zero. m = 2kg. Take R = 5Ω, α = 0.1 T/sec, B₀ = 2T, ℓ = ℓ m, ℓ₀ = 1m, v = 5 m/s.
