The current is to the right through the resistor. A voltage is produced when a magnet moves into a coil of wire. A magnet and a coil of wire can be used to produce an electric current. (b) If instead the magnet (still in the same orientation) was moved to the right, what would be the direction of the current through the resistor? The current is to the left through the resistor. A bar magnet rests outside a wire coil connected to an ammeter showing no current How is a current produced in an electromagnet These are made by coiling wire carrying a current around a magnetic core. SN CU (a) What is the direction of the current through the resistor when the magnet is moved to the left as shown? The current is to the left through the resistor. The wire is connected to a resistor oriented parallel to the axis of the coil. My Notes Ask Your Teacher The figure below shows a bar magnet positioned near a coil of wire, with the north pole closest to the left side. The current is into the page (that is, counterclockwise when viewed from the left). When the switch is closed, what is the direction of the induced current through the resistor? The current is out of the page (that is, clockwise when viewed from the left). A loop of wire with a resistor is concentric with the coil. ![]() My Notes Ask Your Teacher The figure below shows a coil of wire connected to a battery and a switch.
