Hi guys Think you'll fin all you want and more via Hitachi magnet spec sheets without duplicating their work! Their range is extensive. http://www.hitachi-metals.co.jp/e/prod/prod03/prod03.html Also if anybody is interested in full 3D Electromagnetic work I have Cosmos EMS, which is full 3D (though my skills knowledge are definitely far beyond Dr. Meeker's) Jeremy ----- Original Message ----- From: Jiri Vecerka To: FEMM mailing list Sent: Friday, April 02, 2004 3:32 PM Subject: RE: [FEMM] Magnetization curves Hello NdFeB has linear magnetic characteristic with relative permeability around 1,05. Hc depends on used material. Producers provides B and Hc and you can calculate relative permeability from that. This is for cold magnets, with temperature the characteristic change, but I calculate with linear characteristic reduced about 10% of the Hc. B reduces about 12% per 100C for NdFeB. Take a look for example: http://www.vacuumschmelze.de/dbw/public_vac/Homepage_en/$pages/Dauermagnete_ startold Jiri Vecerka > [mailto:femm-bounces@list.foster-miller.net]On Behalf Of > agnaldo@if.ufrj.br > Sent: Friday, April 02, 2004 6:20 AM > Subject: [FEMM] Magnetization curves > > David, thanks for your answer about the vector potentia XY plot, > it was very > usefull to me. > Now I ask, once more, the FEMM people colaboration about another > problem; does > anybody has (or knows how to find)B(H) cuerves for NdFeB and SmCo5?
