... So to maximize this field we need a large wire radius. This means that we should use all the metal into a single turn of wire. This is why the question is flawed: with one single turn we do not have a solenoid! There must be additional restrictions placed on this problem such as a given minimum numb ...

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.
