(a) Radial magnetometers measure radial or normal component of the MFs; (b) tangential magnetometers measure tangential components of MFs; (c) vector magnetometers determine the three orthogonal components at each location, measuring the vector MF; (d) radial gradiometers measure the radial gradient of radial field; (e) tangential radial gradiometers measure the radial gradient of tangential fields; (f) planar gradiometers measure tangential gradient of radial fields.
