8515 Electromagnetic pendulum

Essential item to study electromagnetic interactions. It consists of a linear magnet hanging from a spring and where a spool is located. Starting the magnet’s motion, an electromotive force is induced in the spool which is measurable at the resistor’s ends.
Similarly, making a/c circulate in the spool, the magnet starts its motion.
