What is the magnetic field where the electrons are traveling that results from this 1 A current in the Helmholtz coils? Hint: Evaluate the expression given for the field betwee two Helmholtz coils with the dimensions used in the experiment.

Provide a numerical answer with no units, simply the field in "microtesla", that is in 10^-6 T. For example, if you found 3.4 x 10^-4 T, answer "3400".

What percent of the speed of light are the electrons traveling at? For example, if you found that the electron was travelling at 3000 km/s, since the speed of light is 300,000 km/s, you would have 3000/300,000 = 0.01 or 1 percent.
