Turtle Travel Tips: How Magnets Can Help Us Navigate | Magnetoreception
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 calls in to explain!...

MAGNETS - How Do They 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.

Stern-Gerlach Experiment and spin quantum number : Revealing Electron Spin
The Stern-Gerlach experiment, which took place in 1922, was the most important proof that electrons have spin and that they have a spin quantum number. A stream of silver atoms was sent through an experiment using a magnetic field that...

Ferrofluids
We compare the properties of three iron mixtures: iron and water, iron and oil and a ferrofluid - a mixture of compounds containing iron and oil. First, we look at how iron filings behave when mixed with water and then oil. We then hold...

Magnetic Strength
We use two magnets and a set of scales to examine magnetic field and strength. One magnet is attached to the scales and a second is lowered towards it. When opposite poles are facing each other, the weight on the scales decreases as the...

Forming Iron Sulfide
We examine the different properties of iron and sulfur when they are mixed and when they are chemically combined. When iron and sulfur are mixed they retain their individual properties. When they react chemically to form iron sulfide...
