stract The objective of this experiment is to compare changes in the ax radial magnetic field as the position of a magnetic field sensor is through a current carrying coil. This will be achieved by compa measured values with those obtained by the long and short s equations. It was determined that the current carrying coil experiment is most likely a short solenoid as the measured va closest to the calculated short equation. It is important to determi type of coil in order to better understand the axial and radial com
