There's a magnet in a secure room in central Tokyo. It's an electromagnet, the kind that generates a magnetic field when electrical current flows through it. The last time the scientists who operate ...

You’ve doubtless seen those ubiquitous clock modules, especially when setting clocks for daylight savings time. You know the ...

The bigger the current the stronger the magnetic field and hence the stronger the electromagnet. Hazard Consequence Control measures Water Electric shock Do not set up the experiment near taps ...

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 ...
