... strength of the field. As long as you wrap it in the same direction, the field will continue to increase with each additional coil. Question 3: What would happen if we used a larger voltage source? We would be increasing the current and would thus have a more powerful electromagnet by Ampere’s law. ...

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.
