   Used other than figuratively or idiomatically: see magnetic, deviation.

   • Preliminary experiments with radium of activity 1000 showed that it was very difficult to determine the magnetic deviation of the α rays.

   The difference in angle between magnetic north and the north shown by a compass at any given location and time, caused by interference from local magnetic fields.

3. 3

   Magnetic declination.

   • This angular difference is the local magnetic deviation (Figure C.2). Navigation systems normally work relative to True North and therefore must remove the local magnetic deviation.
