Synopsis

A MVEarthMagnetic is a 3-vector of the Earth's magnetic flux density in a rectangular frame with the z-axis to astronomical North pole, and x-axis towards longitude zero, in internal Units of nano tesla (== 0.00001 G).
It can be constructed with:

A void adjust(Double) function normalises the vector to a length of 1; a get() returns as a Double 3-vector the length and angles of the EarthMagnetic vector; a getAngle() returns a Quantum 2-vector, (uInt) returns the indicated element, and getValue returns the vector.
EarthMagnetics can be added and subtracted.
The multiplication of two EarthMagnetics produces the in-product.

Example

See MEarthMagnetic class.
