Physics and Python stuff. Most of the videos here are either adapted from class lectures or solving physics problems. I ...

ITER has devised the technology that could unlock fusion energy, and they've done so with the aid of a 60-foot magnet. Here's ...

As you may recall from Physics 101, a changing magnetic field (like when you slide a bar magnet through a copper coil) induces an electric current. At planetary scale, Earth’s magnetic field induces ...

Natural crystals fascinate with their vibrant colors, their nearly flawless appearance and their manifold symmetrical forms.

Every breath we take in contains 21% oxygen, the gas that makes life on Earth possible. Oxygen, in its combined oxide state, ...

As with all currents, the induced current creates a magnetic field around itself. Note that this magnetic field opposes the original change. For example, if a magnet is moved into a coil of wire ...
