Josephson vortex

Have you ever seen a tornado or a whirlpool in the water? A Josephson vortex is kind of like that, but much much smaller and it happens inside something called a superconductor.

A superconductor is a really special material that conducts electricity with no resistance at all. Normally when you send electricity through a wire, some of it gets lost as heat, but in a superconductor, all of the electricity just keeps flowing and flowing without any waste.

Now, sometimes in a superconductor, tiny swirling patterns can form. These patterns are called Josephson vortices, and they behave a lot like the whirlpools you might see in water.

Imagine you're looking down at a superconductor under a microscope, and you see that electricity is moving in a circular pattern around and around like a whirlpool. That's what a Josephson vortex looks like!

Scientists are really interested in these little vortices because they can affect how electricity moves through a superconductor. By studying Josephson vortices, scientists hope to learn more about how superconductors work and how we can use them to make better technologies.
