quick physics question

Say magnetic field is pointing into the page and current is going to top of page. Which direction is the force on electrons? right or left?

My thought process was to use the right hand rule. I got the direction of protons to be to the left. So I figured the electrons would go to the right. But according to kaplan the electrons would go to the left, same as the protons? Does that make any sense?

I think Kaplan is correct.

Current is "theoretical" movement of positive charge. So electrons actually move in opposite direction as the current. So electrons are actually moving toward bottom of the page.

Using the right hand rule, force on the protons moving toward bottom of the page would be to the right. So force on the electrons moving in the same direction would be to the left.

yea that makes sense I guess, its just confusing to think that both protons and electrons have force in the same direction, I always thought everything with them was opposite.
