One side of a small, DC permanent magnet motor is connected via a switch to the positive terminal of a battery. The other side is connected to the negative battery terminal via a nichrome wire shunt and a galvanometer. A resistor across the battery and switch provides a path to complete the circuit when you open the switch. farm systems reform act
