Magnetic surface flux : Gauss

Pull force: kg lb

Remark:
1.The Surface Field data is only valid for points along the center axis of the magnet, and assumes a single magnet in free space.
2.The Surface Field data has to do with the value of Br. when the dimension of NdFeB magnets are same.
3.The results show that the measurement value of magnetic surface flux and pull force can not be accurately approximated due to poor consistency of Br.
4.The calculator is intended only for reference, all calculations are approximations and should not be used as the sole source of design data. The factors of your application may change these values considerably. Be sure to test magnets in your configuration.
5.The calculator is intended only for NdFeB magnets, if your want to measure other magnets, such as Ferrite magnets, AlNiCo magnets, please write down the Br value.
