Magnetic Field Strength Calculators

The calculators on this page are appropriate only for “Square 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: in.
L: in.
D: in.
Br: gauss
 
B(z) =  Gauss

Field Strength of a Rectangular Magnet

Z: in.
A: in.
B: in.
L: in.
Br: gauss
 
B(z) =  Gauss

Input Fields

Z = Distance tested from magnet
L = Length of magnet
D = Diameter of magnet
Br = Residual Gauss of magnet

Input Fields

Z = Distance tested from magnet
L = Length of magnet
A = Height of magnet
B =  Width of magnet
Br = Residual Gauss of magnet
