It takes the electrons 1.2 μs to travel around this ring at almost the speed of light; 847,000 times per second.

We know that heat has the oppisite effect, it actually makes the electrons travel faster!

While the electrons are traveling, the helices essentially don't matter.

The freed electrons travel through a wire creating the electric current.

On average, the electrons travel from the cathode to the anode.

In these cases the electrons are traveling at very nearly the speed of light.

At the speed of light, electrons can travel 0.0684 miles (0.11 km) in 0.0000003675 seconds.

Yet a single electron would travel simultaneously though multiple holes, however many were placed in front of it.

Are the field lines actual channels by which electrons travel?

Field lines are not channels by which electrons travel.
