    Hi

    Everyone seems to know what magnetic fields are and that they are caused by electric currents, but i can't seem to find a good reason WHY they are caused by lectric currents.

    Thanks, appreciated

    If we knew what "causes" magnetism, then the next question would be "what causes that?" In other words, if magnetism is a result of some particle, let's say a fictitious "delta particle", then one can ask "what gives this delta particle its characteristics?"

    There will always be a smallest detectable wave/particle/energy that cannot be resolved into more fundamantal components due to limitations of measuring instruments. These small indivisible (at the present time) entities form the basis for scientific laws known as axioms.

    That's all anyone can really say. Does this help?
