Lorentz force velocimetry

Lorentz Force Velocimetry is like playing a game with magnets and water. When you put two magnets together, they either attract each other or push each other away. Water can do the same thing when it moves past a magnet.

Scientists use a big magnet and a machine to create a stream of water. They make the water move past the magnet and measure how fast it's going. The magnet makes the water push, and the machine can tell how strong the push is.

This can help scientists understand how things move in the water, like tiny particles, cells, or even blood cells. It's like playing a game where we can see how things move and how fast they are going.
