#8. The angle between True North and Magnetic north is known as:
#9. The value of magnetic variation on a chart changes with time. This is due to:
#10. Isogonal lines converge as follows:
Isogonic lines, which connect points of equal magnetic declination (the angle between true north and magnetic north), converge on both the True and Magnetic North and South Poles. This is because at the poles, the magnetic field lines are vertical, meaning a compass needle would point straight down into the Earth’s surface, effectively eliminating any declination.
