Rectangular Magnets With Steel Backplate

This tool calculates flux density on the centerline of a rectangular magnet with a steel backplate, at a distance of X from the surface of the magnet. (X must be greater than 0.)

Inputs	Magnet 1	Magnet 2
Length			Distance can be input in any units of measure as long as they are consistent to each other.
Width
Thickness*
Distance X
Br (Gauss)			Must be entered in gauss units.
Gauss at X			Results are in gauss.
*This is the orientation direction (the magnetic field flows through this direction)
