The kinematic approximation becomes invalid when the magnetic field becomes strong enough to affect the fluid motions. In that case the velocity field becomes affected by the Lorentz force, and so the induction equation is no longer linear in the magnetic field. In most cases this leads to a quenching of the amplitude of the dynamo. Such dynamos are sometimes also referred to as hydromagnetic dynamos. Virtually all dynamos in astrophysics and geophysics are hydromagnet… WebbThe total field ranges from 25,000 to 65,000 nanoteslas(nT).[1] To measure anomalies, magnetometersneed a sensitivity of 10 nT or less.
