1. The problem statement, all variables and given/known data After you close the switch, There will be an induced current in the resistance R, Choose one of the following: Direction of current ...... magnitude of current A to B ... decreasing A to B ... increasing B to A decreasing B to A... Increasing 2. Relevant equations Faraday's law lenz's law 3. The attempt at a solution When you close the switch a current in the counter clockwise direction flows in the black circuit thus a magnetic field is created inside the solenoid pointing to the right and increasing with time. Now the red circuit will produce a magnetic field in the other direction, which means the current will be from B to A and decreasing However, the book disagrees( well old exam) It says that it will flow from A to B and decreasing.
