Magnetic Field Calculator

This tool calculates magnetic field strength measured in gauss, on the centerline of a disc magnet or ring magnet magnetized through its thickness, at a distance of X from the surface of the magnet. 

These calculations are only appropriate for "square loop" or "straight line" magnetic materials such as ceramic magnetsneodymium magnets, and samarium cobalt magnets. They should not be used for alnico materials. 

Fill in all of the blank calculation fields, click the calculate button and the results will appear. The necessary geometrical inputs are illustrated in the diagram. Units of measure may be inches or mm, but must be consistent.
