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 ...

Loggerhead turtles “dance” when exposed to food-associated magnetic fields, and their magnetic map may help them return to specific areas after long migrations.

In fact, the discovery actually supports a key part of the theory about how chorus waves work. Using data from the ...

A permanent magnet can magnetize parts of an old CRT television, distorting the image and colours due to the magnetic force on the electrons. A degaussing coil restores the TV to normal working order.

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 ...
