Lenz's Law, Eddy Currents & Induced Electric Field
Two similar circular loops carry equal currents in the same direction. On moving coils further apart, the electric current will
Show answer and solution
Answer: (a)
- Currents in the same direction mean each loop's field adds to the flux through the other.
- Moving the loops apart decreases this flux in each loop.
- By Lenz's law the induced current opposes the decrease, so it flows in the same direction as the existing current.
- So the current increases in both, answer (a).
