29.17: a) When the switch is opened, the magnetic field to the right decreases. Therefore the second coil’s induced current produces its own field to the right. That means that the current must pass through the resistor from point a to point b . b) If coil B is moved closer to coil A , more flux passes through it toward the right. 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

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 ....
