This means that their magnetism is there all the time and cannot be turned on or off as it can with an electromagnet. Converting a magnet to a non-magnet is called demagnetisation. Magnets are ...

(Our planet's magnetic field should look a lot like the field around a bar magnet, but electrically charged particles in the solar wind push against the magnetic field, so the side pointing away ...

How a Generator Works When an electric current flows through a wire, it generates a three-dimensional magnetic force field around the wire, similar to that surrounding a bar magnet. Magnets are ...

Many people will remember experiments in school with iron filings and bar magnets to unveil their magnetic field. It's not quite so easy to capture the magnetic field of the Milky Way though.

A flower-shaped structure only a few micrometers in size made of a nickel-iron alloy can concentrate and locally enhance ...

Using an XMC1100 microcontroller development board and a TLV49 3D magnetic sensor, the device is able to track the poles of a magnet in real-time and produce an approximation of what the field ...
