Linear Permanent Magnet

Permanent Magnet with linear characteristic

 Description The Linear Permanent Magnet component is a flux tube of fixed length and cross-sectional area that models a linear permanent magnet using material data. The Hard Material parameter specifies the name of a record of class Hard Magnetic Material, which defines the magnetic material. A record of that class, with the corresponding name, must exist in the model, either at the same or higher level. Records of typical materials are in the palette Magnetic > Material > Hard. The Use default material boolean parameter, when true, sets the name of the Hard Material parameter to HardMaterial1, which corresponds to the default name assigned to a record of the appropriate class.  To use a different name, uncheck the box and enter the name for the parameter that appears.
 Equations $\mathrm{\Phi }={\mathrm{\Phi }}_{p}=-{\mathrm{\Phi }}_{n}=BA$ ${V}_{m}={V}_{{m}_{p}}-{V}_{{m}_{n}}=H\ell$ $B={\mathrm{\mu }}_{r}{\mathrm{\mu }}_{0}H-{B}_{r}$
