What does the arrow of the Net Magnetic Vector (NMV) indicate?

The longer the arrow, the higher the signal-to-noise ratio (SNR)
The length indicates the field strength of the main magnetic field.
Direction of the main magnetic field
The speed of the magnetic moments
The longer the arrow, the higher the signal-to-noise ratio (SNR)

The length indicates the field strength of the main magnetic field.
