What affects the direction of the current moving through a wire? check all that apply. -the direction the wire moves in -the thickness of the wire -the direction of the magnetic field -the type of magnet -the direction of the needle on an ammeter

I am definitely sure that these factors affect the direction of the current moving through a wire: 
the direction the wire moves in
the direction of the magnetic field
the direction of the needle on an ammeter
You can check it by using Right-Hand rule which is very useful when you need to find how charges move.
