AI Thread Summary
When two electric currents collide, such as those flowing in opposite directions in a wire, they can interact based on electromagnetic principles. If currents are induced by moving magnetic fields, one current may flow to the left while the other flows to the right. According to Maxwell's equations, the collision of these currents results in their densities summing to zero, effectively canceling each other out. In practical terms, this could lead to a buildup of electrons in the space between the two opposing currents. The overall effect is a complex interaction rather than a simple collision.

What would happen i you forced two Electric currents to collide? Say we have two currents where one current flows "up" the other one "down", and they hit each other at a certain Place?

The closest situation I can think of that comes close to what you are asking is where two parallel circuits come join together at a junction. In that case, the currents simply add together.

Lets say we had a copper wire, and two magnets. So we conduct currents (electromagnetic induction) with the magnetic fields. If the magnetic fields moves uppwards then down, the current of electrons will flow to the "left". If we move the magnetic field down and up, the current will flow to the "right". Then couldn't these two currents collide, when they are traveling towards each other? From the left end of the wire, current flows, and then from the right end of the wire current flows.
 
Maxwells equations are linear, so if you get a current density of +j colliding with a current density of -j then they sum to 0.

I believe you'd just make the electrons bunch up in between the magnets.
 
It may be shown from the equations of electromagnetism, by James Clerk Maxwell in the 1860’s, that the speed of light in the vacuum of free space is related to electric permittivity (ϵ) and magnetic permeability (μ) by the equation: c=1/√( μ ϵ ) . This value is a constant for the vacuum of free space and is independent of the motion of the observer. It was this fact, in part, that led Albert Einstein to Special Relativity.
