Unformatted text preview: b to point a . c) If the variable resistor R is decreased, then more current flows through coil A , and so a stronger magnetic field is produced, leading to more flux to the right through coil B . Therefore the induced current must produce its own magnetic field to the left to oppose the increased flux. That means that the current must pass through the resistor from point b to point a ....
