The lodestone is a magnet right? since all magets and magnetic materials are conductors of eletricity, does the loadstone conduct electricity? and what is the loadstone made of?
Not all magnetic materials conduct electricity, only the ones made from metals or metal alloys. Ceramic magnets may or may not conduct, depending on their composition. Lodestone is made of a mixture of various minerals, but the magnetic one is Fe304, which by itself is magnetic but non-conducting I believe.
Not paper but we used to use sheet copper
i think you can get make your own gaskets, I believe that Pep Boys or Schucks carries these kind of things at their Main Warehouse store It is a risk to do such things, I would prefer to spend the extra money to get the right gasket vs hoping that you cut it correctly and then taking the risk of damaging more than one of them
At a microscopic ( atomic) level all materials are conductors of electricity in that electrons are moving. But at a macroscopic level this is only true if electrons are free to move through the bulk of the material. The statement all magnetic materials are conductors of electricity is completely false. All that is needed to be magnetic is that the various atoms can be oriented so that their individual magnetic fields add together rather than being pointed in random directions. Most magnets contain iron in various forms ( although nickel and cobalt also work well) So all iron oxides are to varying extents magnetic. Lodestone is just one of many iron oxides. Now because the iron is bound to oxygen molecules the electrons are not free to move through the material in bulk so it is a poor conductor of electricity.
