Explore the fascinating world of clean energy with this step-by-step DIY magnetic generator build. Learn how everyday items ...

Discover how to build a simple electric train using just a copper coil, an AA battery, and disc magnets in this step-by-step science experiment. Starting with basic materials, watch as we construct ...

This is a small motor made from simple household supplies. A battery pushes current through a coil of copper wire under the influence of a permanent magnet. The coil spins freely when operating.

A strong permanent magnet acts as a simple pendulum, swinging back and forth while hanging from strings. A copper plate underneath the magnet can be moved up to tune the eddy current damping. Swing ...

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, ...

Hybrid magnet for "neutron scattering" experiments to be built. The planned magnet will produce a magnetic field between 25 tesla and 30 tesla -- more than half a million times stronger than the Earth ...
