Thanks for the awesome video! So for the case where we turn off the magnetic source and run the electric source, my understanding is that since we have a current going through the liquid metal, this would generate a magnetic field that would circle around the flow of electrons (using the curl right hand rule). However, this would not generate a magnetic force, since this "circling field" essentially cancels out any forces. In order to generate a force, we would need a magnetic field travelling perpendicularly through the electric current (based on fleming's right hand rule). Is my thinking correct?
Yes. It's like the the way it would work in a small permanent magnet motor. If we take the magnet out and apply current to the motor, it would not turn even tough the current passing through the coil of motor creates a magnetic field.
Yes it can work if you dissolve salt(NaCl) or something similar to make it more conductive. The problem with this method however is that the current will also break down the water into H2 and O. And since it's not as conductive as a metal, it's going to require a higher voltage. But it will work.
You are very underrated I have only recently discovered your content and cannot stop watching I'm about to watch every video you've ever made
This was extremely informative and interesting. Quality stuff

Binging. But circular isn't a rectangle. Don't worry I already subbed and liked the last 5.
ripper vid thanks mate!
Magneto hydrodynamics
IS POSSIBLE THIS WAY?
hum, will water work? not as conductive as metal but it can still carry current
Yes it can work if you dissolve salt(NaCl) or something similar to make it more conductive. The problem with this method however is that the current will also break down the water into H2 and O. And since it's not as conductive as a metal, it's going to require a higher voltage. But it will work.
There's a video titled "Magnetohydrodynamics - Propelling Liquid Metal with Magnets!" on the Tech Ingredients channel where they use water.
Will mercury work?
Yes mercury can also be used instead of hot molten metal
