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

Magnetic force exists thanks to relativistic transformation of electric force. See special theory of relativity to learn more about this.
