For the first time, scientists have built a fusion experiment using permanent magnets, a technique that could show a simple way to build future devices for less cost and allow researchers to test new ...

The Princeton Physics Lab has built a Stellarator nuclear fusion reactor prototype using permanent magnets. This is a scientific first that enables mostly off the shelf magnet for simple and low cost ...

Magnets, how do they work? Although the quantum mechanics behind ferromagnetism are by no means easy, a few simple experiments can give you a good grasp of how magnets attract and repel each other, ...
