Using the right-hand rule, when the thumb points in the direction of the current, the fingers will curl in the direction of the magnetic field.
 
true or false

Historically, this is true.

However, if the "current" is defined as the direction that electrons are travelling, it isn't. The difference occurs just because an electron has a negative charge. I only mention this (at the risk of confusing you) so that you can make sure you are looking at the correct situation.
