To determine the direction of the induced current in a circular coil when a bar magnet falls towards it, we can follow these steps: ### Step 1: Identify the Orientation of the Bar Magnet The bar magnet has two poles: a north pole (N) and a south pole (S). Depending on which pole is closer to the coil, the magnetic field and the induced current will differ. ### Step 2: Analyze the Case of the North Pole Falling Towards the Coil If the north pole of the bar magnet is falling towards the coil: - The magnetic field lines from the north pole are directed away from the magnet. ...
