So from what I understand instanteous force has direction towards/centripetal to the wire, what I fail to understand is if this force is constant and if not why.
I understand how the centripetal field exists around the wire does that mean the force is towards the wire. How would this affect the force being constant(acceleration in centripetal stays same but for this it's going from down to centripetal).
Ya I am unsure what the direction on the force will be because the field is on a straight wire going around the wire while the electron is going down, and I am unsure of whether force is constant.
