Dirac`s Conception of the Magnetic Monopole, and its Modern Avatars
... With considerable satisfaction, Dirac concluded that not only can magnetic monopoles exist, but if they do, then electric charge in the Universe is quantised. The minimum electric charge is determined by the value of the Inagnetic charge. Having presented this extraordinary insight, Dirac concluded ...

... The flux out the cylindrical box (you could have chosen also a square box doesn’t matter here) is Φ= Q/ єo according Gauss’s Law; if surface density σ =Q/A is given we can have that Q= σ A so that the flux is Φ= Q/ єo = σ A/ єo. Now definition of Flux is Φ= E2A (in this simple situation the field is ...

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.
