Tiny magnetic "flowers" engineered by physicist Anna Palau are redefining how we manipulate magnetic fields. These ...
A flower-shaped structure only a few micrometers in size made of a nickel-iron alloy can concentrate and locally enhance ...
Because of the repulsion force, they aren’t hanging ... This will create a magnetic field, and other wires with electric current will experience a magnetic force. Imagine you have two parallel ...

Bismuth is so strongly repelled from magnets, it levitates. How?The repulsion between bismuth and the magnets ... "In paramagnets, when you apply a magnetic field, spins in that material will align with the field in proportion to its strength," he said.
A permanent magnet is always magnetic. It has an invisible magnetic field. Only certain materials, such as iron, feel a magnetic force. Permanent magnets can come in lots of different shapes and ...
But, there may be another way, albeit a rather special case, where a magnet can not only be levitated, but locked in place using a rotating magnetic field. The video shows a demonstration of how ...
Scientists know well how conventional materials conduct heat. However, things are not as straightforward under extreme ...
The students use models and micro:bit sensors to investigate magnetic fields created by simple magnets, electrical circuits, and elecgtromagnets to gather evidence to explain how a maglev train ...
