Before calculating the magnetic field, please enter the remanence value of the magnetic material (Br in T), the geometric dimensions (R and H in mm), and the coordinates (X, Y, and Z in mm) to calculate the magnetic field at any point.

To calculate the magnetic field of a ring magnet, the ring magnet (OD × ID × H) can be treated as two disc magnets: one magnet (Disc Magnet 1) wiHth the dimensions OD × H and another magnet (Disc Magnet 2) with the dimensions ID × H. The magnetic field of the ring magnet is equal to the difference between the magnetic fields of the two disc magnets:

Magnetic Field of the Ring Magnet = Magnetic Field of Disc Magnet 1 − Magnetic Field of Disc Magnet 2
