Bohm diffusion

Bohm diffusion is like how you move when you play tag with your friends. Imagine you are playing in a big field with lots of friends. When you start to run, you move quickly in a straight line towards the person you are trying to tag. But as you get closer, you slow down a little bit because you have to be more careful not to bump into them or trip. Eventually, you tag them and then you both start running again.

Bohm diffusion is like this because it is how particles move in a plasma (a special kind of gas with charged particles) when there is a magnetic field. The magnetic field forces the particles to move in a straight line at first just like when you start running in the field. But as they get closer to other particles or obstacles, they start to slow down a little bit and move more randomly. This is called diffusion because it is like particles spreading out and getting more dispersed. The slowing down and random movement is caused by interactions between the particles and the magnetic field. Over time, the particles can move very far away from where they started, just like how you can run very far away from your starting point while playing tag with your friends.

So, in summary, Bohm diffusion is like particles moving through a plasma in a magnetic field, slowing down and moving more randomly as they get closer to other particles or obstacles, and eventually spreading out over a large area.
