Hall effect lab manual

The Hall field Ey can be measured by the voltage difference between points a and byh, where h is the sample height. The total current flowing through the strip is I =J ×(hδ). Thus, in terms of laboratory quantities we have the equivalent definition of RH in terms of the Hall voltage and the current: IB R V H H δ Δ = Where, again, δ is the thickness of the www.doorway.ru Size: KB. ENGINEERING PHYSICS LAB SYLLABUS S. No. List of Experiments Page No. Date Remarks I Determination of charge carrier density –Hall effect. 3 II Determination of frequency of a given tuning fork – Melde‟s experiment. 7 III Magnetic field along the axis of current carrying coil - . Connect the circuit shown in Fig. X-3 and insert the Hall-effect sample holder between the magnet pole pieces. Note that a Lab Pro, data acquisition system, has been added to this experiment to ease the data taking in this experiment. The gaussmeter and micro-voltmeter used in this experiment have analog www.doorway.ru: R A Webb.

Fig.1 Schematic representation of Hall Effect in a conductor. CCG - Constant Current Generator, J X - current density ē - electron, B - applied magnetic field t - thickness, w - width V H - Hall voltage. If the magnetic field is applied along negative z-axis, the Lorentz force moves the charge carriers (say electrons) toward the y-direction. Fundamentals of Electric Propulsion: Ion and Hall Thrusters March The research described in this publication was carried out at the Jet Propulsion Laboratory, California Institute of Technology, under. The Hall effect probe is a thin slab of indium arsenide, InAs, cemented to a piece of fiberglass. A four lead cable is attached so that the necessary electrical circuit can be used to detect the Hall voltage. The probe is equipped with a bakelite handle that is used to hold the probe in place. The white and green.

2. Hall Effect Experiment. This part describes the Hall Effect apparatus, as well as the procedures for computer control and data collection. Apparatus Equipment List. Figure 1: The Hall Effect Apparatus. Figure 2: Hall Probe Detail Equipment. Alpha water-cooled magnet and power supply (Turn on water before turning on power supply. This manual may be considered as two parts: Chapters 2 through 5 present the basic information needed to apply Hall effect devices. Chapter 6 brings this information together and relates it to the design and application of the Hall effect sensing. The Hall Effect experiment determines the sign of the charge carriers in current flow. A current can be thought of as a negative charge moving in one direction (Fig. 1a) or as a positive charge moving in the opposite direction (Fig. 1b). To determine which it actually is.
