    Relation between H and B fields, and D and E fields

    Thanks for the replies, good to know my thinking was right! It seems strange however that E and D have different units in one system of units, and the same units in another one. I mean, one could never define another system of units where a Newton had the same units as coulomb, right?

    Relation between H and B fields, and D and E fields

    Hey! I am having some trouble understanding why the magnetic flux density B and the magnetic field strength H does not have the same units. I mean, as far as I understand, the H field is just the B field with the magnetic properties (magnetization) of the material taken into account? Isn't...

    Data on CoPtCrB

    Hey! Im doing a project at university about storages medias. I come across a matter called CoPtCrB used as the magnetic media in for instance harddrives. I have not been able to find any information like density and such though, and I need those data. Can someone in here direct me to some facts...
