Magnetic Field Strength Calculators
The calculators on this page are appropriate only for "Squre Loop", also known as "Straight Line", magnetic materials such as neodymium-iron-boron, ferrites and samarium cobalt magnets. They are not for use with alnico materials.
Field Strength of a Cylindrical Magnet
Z = Distance tested from magnet
L = Length of magnet
D = Diameter of magnet
Br = Residual Gauss of magnet
Field Strength of a Rectangular Magnet
Z = Distance tested from magnet
L = Length of magnet
A = Height of magnet
B = Width of magnet
Br = Residual Gauss of magnet
