If electricity possible to made only by using magnets (Lorence force) then how electricity was maded for creating with electromagnets the permanent magnets?
Any history regards this?
If magnets was taken from earth, then me bothering question how strong magnetic properties they have? And how many times now artificialy created magnet is stronger than the one discovered probably 100 and more years away of same mass?
Why now all magnets are magnetized with electromagnets rather just using goted from Earth or maybe first magnets (do not artificialy magneted) was from iron or from same matterial which now used in say speakers?
