Dice are about the simplest machines possible, and they’ve been used since before recorded history to generate random numbers. But no machine is so simple that a little needless complexity can’t make ...
Magnetic levitation demonstrated using a Dremel tool spinning a magnet at 266 Hz. The rotor magnet is 7x7x7 mm3 and the floater magnet is 6x6x6 mm3. This video show the physics described in the work ...
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 ...
An MIT research team has observed a previously unseen form of magnetism, one that sits outside the familiar categories of ferromagnets and antiferromagnets. The discovery, termed p-wave magnetism, ...
The new miniaturized structure requires a few thousand times less power than larger magnets and it could help bring ...
