The Effects of Working in a Magnetic Field, San Diego State University (more info) This Flash animation delves into magnetic declination, the angle between magnetic north and true north. To see declination values, enter your locale declination in the input box (positive for east declination, negative for west declination). The true north on the frame will then reset to take into account inputted values, with true north shifting to the east for positive values and to the west for negative values.
