As the pendulum’s magnet accelerates towards the electromagnet’s core, the Hall effect sensor registers an increase in voltage. The voltage peaks as the pendulum passes overhead, and as soon ...

The device sure looks like an electromagnet made with magnet wire and a steel core. But when he shows the ends of the core, you’ll see that the side that attracts aluminum has a copper ring ...

A coil with an iron core is called an electromagnet. The iron core increases the coil’s magnetic field strength. A simple electromagnet is made by coiling wire around an iron nail. An iron core ...

Electromagnetic fields are everywhere ... “Spinning like tops, the electrons circle the nucleus, or core, of an atom. Their movement generates an electric current and causes each electron ...

Sumitomo Electric has expanded its lineup of powder magnetic cores for motors and has added new material data to the ...
