**Q21.** Assuming that coils 1 and 2 will share the same **B**, what is the direction of the induced current through the resistor of coil 2 as the switch of coil 1 is closed? Use the 4-step method, taking the perspective "from the right".[Diagram: Illustration shows two coils, labeled 1 and 2, wound around a common core. Coil 1 includes a switch labeled "close switch," indicating that closing the switch affects coil 2, which has a resistor.]Explain here.**A question to ponder...** current is only induced if the flux within the coil is changing. Would a current be induced in a straight wire segment in the vicinity of a changing magnetic field?

By the Lenz law the current induced in the coil is in the direction such that it opposes the Induced Emf. so when the switch is closing there is a flux change in the coil 1 as shown in the figure. North pole in the left side of the coil 1 so there will be a south pole in Right side of the coil 1 at the time of closing switch the Intensity of the south pole in right increases so to opposes this change a South pole will be generated in the Left part of the coil 2 so the the flow of the current will be as shown. From left to right in the resistance. when the switch is closed then there is not any change in the magnetic flux so no induced current hence there will not be any current after the switch is closed.
