In magnetic reconnection, adjacent magnetic field lines break and snap together to form new lines. This process converts ...

Iron is magnetically soft – it can be easily magnetised and demagnetised. Magnetic fields lines are invisible but they fill the space around a magnet where the magnetic forces work on magnetic ...

The video explains the concepts of magnetic, electric, and gravitational fields using simple demonstrations. It shows how iron filings reveal the magnetic field around a magnet, how charged objects ...

Magnets are also surrounded by a similar three-dimensional field ... the lines of magnetic force surrounding the magnet. The simplest generator consists of just a coil of wire and a bar magnet.

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 ...
