... The curious thing about the magnetic dipole field (in this particular configuration) is that if m = mi + 0j, then the constant m can be factored out in front of the remaining vector expression. Thus, all magnetic dipole fields are equivalent, except for strength. The field lines should always match, ...

Hall effect
The Hall effect is the production of a voltage difference (the Hall voltage) across an electrical conductor, transverse to an electric current in the conductor and a magnetic field perpendicular to the current. It was discovered by Edwin Hall in 1879.The Hall coefficient is defined as the ratio of the induced electric field to the product of the current density and the applied magnetic field. It is a characteristic of the material from which the conductor is made, since its value depends on the type, number, and properties of the charge carriers that constitute the current.
