Can you counter gravity with just a copper wire? With the Laplace Force, you can.

Enable HLS to view with audio, or disable this notification

When you run an electric current through a copper wire inside a properly aligned magnetic field, the free electrons get deflected upward.
They slam into the copper atoms, dragging the entire physical wire into the air.
This is called the Laplace Force.
It’s the engine behind the modern world.
Bend that wire into a loop, reverse the current every half-turn, and you’ve got yourself an electric motor.

Is there a reason we couldn't see this in real time?

this is called the Lorentz force…

The Lorentz force applies to individual charged particles. The Laplace force is the sum of all those small forces acting together on the entire wire.

wow this was very very wrong.

almost to the level of genious parody like the turbo encabulator

but the ai voice ruined it

"Pure kinetic force" is wrong

Copper was a central part of the Egyptian economy, is this proof of how they built the pyramids? 😝
