... there is no current in the loop, even if the magnet is inside the loop. However, when the magnet is brought near (or pulled away from) the loop, the ammeter needle deflects indicating an induced current in the loop produced by an induced emf (Figure 1b). From these observations, Faraday concluded th ...

... The brush is pushing against one of the half rings so electricity can flow from the brush into the ring. This gets it into the loop. It flows around the loop to the other ring where it flows into the brush and then back to the battery. Thus there is a path for the electricity to flow. The loop is co ...

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.
