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

Hank reaches the fourth and final of the four fundamental interactions in physics: electromagnetism. In this part, he teaches us about the electrostatic force, which builds up a charge in an object and can travel in the form of an...

In this video Paul Andersen explains how electromagnetic induction occurs when the magnetic flux of an object changes. The magnetic flux is product of the surface area perpendicular to the magnetic field and the magnetic field strength....

Gems are more than just pretty rocks!

From wasps nests to nuclear reactors. Here are just a few clever ways archeologists figure out how old something is.

Phil takes us for a closer (eye safe!) look at the two-octillion ton star that rules our solar system. We look at the sun's core, plasma, magnetic fields, sunspots, solar flares, coronal mass ejections, and what all of that means for our...

There's a region of Earth's atmosphere known as the South Atlantic Anomaly, and it’s one of the most dangerous near-Earth areas of space, both for satellites and humans.

Astronomers have announced the Juno space probe’s first findings from Jupiter!

Elon Musk thinks that we can make Mars habitable by nuking it. But would that really work?

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.

Jessi brought one of her favorite toys to the fort, a magnet! Let's see what it can stick to!

New ReviewIf you're lost in the woods, your best chance of finding your way might be a tiny magnet.

New ReviewThis colorful video program takes a look at the many different types of forces. Magnetic, electric, and gravitational forces are all explored. Special emphasis highlights how these forces impact our everyday lives. This video correlates...

Brain scans enable Psychologists and Neuroscientists to look inside the brain without having to open the patient's skull. In this video we cover four key types of brain scan that every Psychology student needs to know: 1) Computerised...

Not only do they describe every electrical and magnetic phenomenon, but hidden within these equations is a fundamental truth about the nature of light, and why it is the ultimate speed of the universe. We...

Stars represent a celestial battle of two opposing forces, gravity trying to collapse the star, and radiation pressure trying to explode the star. But it comes to an end close to the time that it runs out of fuel. Gravity...

Science Kids Birds and Bird Migration V1-0004

Birds have an extraordinary ability to navigate during migration, utilizing a combination of internal compasses and maps. Studies have shown that birds can find their way home over great...

How to catch the Northern Lights

The magnetic barrier that protects Earthlings from radiation almost collapsed some 565 million years ago. Here’s what saved it.

Pupil outcome: I can describe how magnets can attract magnetic materials, as well as attract and repel other magnets. Key learning points: - All magnets have a north–seeking pole and a south–seeking pole. - Unlike magnetic poles attract...

Pupil outcome: I can plan an experiment to test the strength of an electromagnet and explain how different factors affect the strength of an electromagnet. Key learning points: - The more turns of wire in the coil of an electromagnet,...

Pupil outcome: I can describe how to make a magnet using an electric current. Key learning points: - When there is an electric current in a wire, there is a magnetic field around the wire. - When there is an electric current in a coil of...

Pupil outcome: I can describe how renewable energy resources can be used to generate electricity. Key learning points: - Renewable energy resources will not run out because they are replenished more quickly than we use them up -...
