Flux Density Calculator for Disc Magnets with Steel Backplates

This tool calculates flux density on the centerline of a disc magnet with a steel backplate, at a distance of X from the surface of the magnet.

(For your convenience, you can compare two magnets here.)

Inputs	Magnet 1	Magnet 2
Diameter			Distance can be input in any units of measure as long as they are consistent to each other.
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)
