Magnets are everywhere in our daily lives, even if we don’t always notice them. From holding up notes on the fridge to powering complex machines, magnetism plays a crucial role in technology, science, ...

Magnetism is slightly weird. Iron becomes magnetic because lots of electrons agree to align their individual magnetic moments. If you hit a thin layer of iron with a strong, very short pulse of light, ...

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 ...

Magnetism is a natural force, one that works at a distance. Magnets get their force from magnetic fields created by the atoms within the metal. Magnets are useful for things like turbines we use to ...
