WebMagnetic declination, or magnetic variation, is the angle on the horizontal plane between magnetic north (the direction the north end of a magnetized compass needle points, corresponding to the direction of the Earth's magnetic field lines) and true north (the direction along a meridian towards the geographic North Pole ). WebAnswer (1 of 5): Well, since a compass needle has physical interia, it can not respond to rapidly changing magnetic fields. An AC (alternating current) current has a magnetic field that also alternates at the frequency of the AC (typically 60 or 50 Hz) and it net magnetic field (over the long ter...
