Hey guys.

2007 HSC, Q13.
An electron is moving near a long straight wire. WHen a current is applied to the wire, the electron experiences a force in the same direction as the current flow in the wire.

What was the electron's initial direction of motion?

Please help! I don't understand this question.
Please no 'use right hand palm rule' answers, cause that ain't gon help- I don't understand it so would greatly appreciate if someone could explain.

Thanks.
