Physics F 5: Electromagnet - SlideShare
An Electromagnetic Relay A device that uses a small current (Circuit 1) to switch on another circuit that carries a bigger current (Circuit 2). It thus acts like a switch. When the switch is closed, the soft-iron core becomes electromagnet. The iron rocker arm is attracted to the electromagnet on the central pivot and pushes two contacts together.

Electromagnets - Lesson - TeachEngineering
Students complete the grand challenge of this unit and design an electromagnet to separate steel from aluminum for a recycler. In order to do this, they compare the induced magnetic field of an electric current with the magnetic field of a permanent magnet and then make the former look like the latter. They discover that looping the current produces the desired effect and find ways to further ...
