WebThe Hall Effect Lennon O Naraigh, 01020021 Abstract: This experiment studies the Hall effect – the production of an E field in a conductor due to the presence of both current and a B field – in semiconductor materials. Both an electromagnet and a ferromagnetic material will be used as sources of magnetic field. Webeﬀect is known as the Hall eﬀect, and is the basis of many practical applications and devices such as magnetic ﬁeld measurements, and position and motion detectors. With … The Hall effect is due to the nature of the current in a conductor. Current consists of the movement of many small charge carriers, typically electrons, holes, ions (see Electromigration) or all three. When a magnetic field is present, these charges experience a force, called the Lorentz force. When such a magnetic field is absent, the charges follow approximately straight paths between collisions with impurities, phonons, etc. However, when a magnetic field with a perpendicular co… green beans for 100 people
