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 ...

Martin told me she would army crawl up to the turtles on the sand and dab around their eyes with a foam swab, soaking up the ...

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.

Scientists have discovered a surprising magnetic spin phase where order and disorder mix, challenging old ideas.

The magnetic field lines of a bar magnet can be viewed by using compasses or by shaking iron filings onto a platform above the magnet. Place the magnet on top of the paper in view of the document ...
