JB said to Jean Naudin that Laminations should be used for the coilcore and to you he said you should use ductile iron for coilcore and and magnet poles.If you use ductile iron is this then not the reason why the coilcores because of the rapid change of the poles get hot?Is there a thread or information about the diffrence from magnetmaterials and why Barium works and Strontium not.Do you know what percentage of Ba and ferrite has to be?When you use electromagnets what kind of duty cycle should they have?
Thanks
