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 ... WebA Helmholtz coil is a parallel pair of identical circular coils separated at a distance equal to the radius of the coil and wound in such a manner that current flow in the same direction in both the coils. The Helmholtz coils produce a uniform magnetic field between the coils. The coil was designed and built in COMSOL Multiphysics.
