Dear Sirs,

This image is of 2 permanent magnets of the same volume, 54 cubic inches. On numerous websites that sell magnets, I can use their flux density calculators to calculate the magnitude of the magnetic flux density of the rectangular magnets but none have a calculator for an arc magnet, the magnitude of the flux density of the rectangular magnet at .001 inches from the rectangular magnet is Br = 4010 Gauss or .401 Tesla. My question is, given that the volume is the same for the 2 magnets will the magnitude of the magnetic flux density of the arc magnet be the same as that of the rectangular magnet. Also, where might I find equations to do magnetic flux density calculations of arc magnets. Any help would be greatly appreciated. Thanks. Sorry about the title screw up
