    Almost certainly not Since the invention of the magnetometer in the 1830s the average intensity of the magnetic field at the Earth's surface has decreased by about ten percent We know from paleomagnetic records that the intensity of the magnetic field decreases by as much as ninety percent at the Earth's surface during a reversal But those same paleomagnetic records also.Oct 27 2015 The coiled wire will generate a magnetic field when an electric current passes through it however the magnetic field disappears the moment the current stops Electromagnets need electricity to work Their usefulness lies in the ability to vary the strength of the magnetic field through controlling the electrical current in the wire.
