Discover how electron spin creates tiny quantum magnets and how exchange interactions align these spins in ferromagnetic materials like iron, cobalt, and nickel. Learn about magnetic domains and how ...

Cutting a bar magnet in half won't get rid of its poles. It'll just produce two magnets, each with a north pole that will be attracted to the other magnet's south pole, and vice versa. It's this ...

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, ...

Metals are the only substances that are magnetic. But some metals are magnetic and some are not. The most common magnetic metal is iron. You don't see too many objects made of pure iron but you do see ...

Okay, since we're on the topic, I have a slightly tangential question... How do you make one-way magnets? Or can you? I dismantled a hard drive a while back, and the two magnets inside pulled VERY ...
