In this video Paul Andersen explains how current moving through a loop of wire can act as an analog for a magnetic dipole. Magnetic dipoles (like compass needles) respond to magnetic fields created by other magnets.

In this video Paul Andersen explains how a magnetic force arises when magnets or moving electric charges interact with one another. A magnetic dipole will orient towards a magnetic field. When an electric charge is moving it will...

Magnets are amazingly strong... but there's a very easy way to destroy them. All you need to know is a little bit about ferromagnetism, paramagnetism, and temperature!

Hank builds a simple electric motor just powerful enough to make a small screw spin, but also strong enough to blow your mind.

Maybe you've seen a shooting star, a bright streak of light that zips across the sky! But did you know that those shooting stars are actually rocks falling from space? And sometimes you can find them on the ground! Find out how...

When people travel a long distance, they'll usually use a map. But there are lots of animals that travel really long distances, too, and they can't use maps... so how do they not get lost? Our friend Dr. Turtleman...

The planets in our solar system have a very specific order. But have you wondered why they have the order they do?

How do magnets work? Why do they attract and repel at long distances? Is it magic? No... it's quantum mechanics, and a bit more, as we explain in this, the longest MinutePhysics video ever.

NASA's Tandem Reconnection and Cusp Electrodynamics Reconnaissance Satellites (TRACERS) mission will study "magnetic reconnection and its effects in Earth's atmosphere," according to the Goddard Space Flight Center....
