Objective: Determine the magnetic field generated by coils of various lengths
The magnetic flux density inside a long cylindrical coil is directly proportional to the current through the coil and how close together the coil windings are, but is not dependent on the radius of the coil as long as the length of the coil is comparatively much greater than its diameter. That will be demonstrated in this experiment using two coils of different diameter and another coil in which the separation of the coil windings can be increased or decreased.
