Welcome to PF.

Other than via thermal noise, how do you make this happen? What is driving those electrons in two different directions?

What happens when electrons flow in two opposite directions in an electrical circuit?

If the electrons do it alternately, it is called alternating current, AC, as is used to distribute electrical energy over transmission lines.

If the electrons do it at the same time, equally, they cancel, so there is zero net current.

What if one current bigger than the other

What if one current bigger than the other

Then the difference current will be seen, flowing in one direction or the other.

What happens when electrons flow in two opposite directions in an electrical circuit?

When electrons flow in two opposite directions in an electrical circuit, it typically indicates that there is an alternating current (AC) situation where the direction of electron flow reverses periodically.

You cannot have current flowing in two directions in a single conductor. At least not in any circuit I've ever seen. Even if you could somehow rapidly connect two conductors such that the current flowing through them is opposite of each other, the circuit would rapidly 'correct' itself and the current would end up flowing one way only.

It happens that you discover (again) the branch of physics named "electrostatics".
https://en.wikipedia.org/wiki/Electrostatics

When you have a material that allows charges to circulate, i.e. when charges (such as electrons) can change position, for example by placing positive charges at both ends of a plastic rod, the electrons on the rod move towards both ends.

Of course, unlike electricity, when the electrons have finished moving, there is no current any more (the situation becomes "static").

The positive charges at both ends of the rod are eventually neutralized by the electrons that have migrated (or at least the positiv charge is lowered), and the rod's charge at the middle become positive due to the lack of electrons.

At the same time (at a specified point in the circuit), or at different times?

As a wild guess, which might be incorrect, you might be considering a multi-loop circuit in which a certain point is "shared" by two different loops. If you consider the two loops independently, they might lead to currents in opposite directions at the point in question. The actual current at that point is the sum of the two currents, taking into account any difference in +/- signs.

Since the OP has not been back in 2 weeks to clarify their question, I'll go ahead and close the thread for now. @Omar Ibrahim -- If/when you return, please send me a Personal Message (PM) if you want this thread reopened. Your question is not well-formed, but we are happy to try to clear up your confusion some more. Thanks all for trying to help the OP.
