MAGNETIC FIELD IN HELMHOLTZ COIL

A helmholtz arrangement consists of a pair of identical coils placed symmetrically along a common axis. A fairly uniform magnetic field can be produced in this setup when they are separated by a distance equal to their radius and having equal currents in the same direction flowing through them. In the present setup, the spatial distribution of the magnetic field of a pair of identical coils in helmholtz arrangement and superposition of the individual fields by the coils is investigated using a digital gaussmeter with axial probe
