In this experiment, we can demonstrate that no net magnetic force acts on a magnetic dipole in a region of uniform magnetic field.
To show that a net magnetic force on a dipole exists only in the presence of a magnetic field gradient, a spatially varying field.
To determine the magnitude of the magnetic moment of the dipole by measuring the magnetic force in the field gradient dB/dz. and The basic physics relationship is:
To examine the axial magnetic field gradient of a single current carrying the loop.
