Measurement and instruments - Lab Report Example on-chip Hall voltage generator for magnetic sensing, a Schmitt activate to offer switching hysteresis for noise denial, a comparator that amplifies the Hall voltage, and output open collector. An internal regulator is used to offer temperature remunerated supply of voltage for internal circuits and enables a large operating supply choice, When current flows through a piece of metal, the voltage can be measured perpendicular to the flow of current and the voltage should equal zero under no influence of a magnetic field (PopovicÃŒ , 74). When a magnet field is introduced perpendicular to the flow of current a voltage is induced. If you reverse the polarity of the magnet the polarity of the induced voltage will reverse. The operation is ignited when the device is placed in a magnetic field. When the material is placed in a magnetic field, the flux lines of the magnet and exerts a force on the material which is a semiconductor. This leads to deflection of electrons and charges. Movement of charge carries is due to magnetic force that they experience (PopovicÃŒ , 204). When current flows through a piece of metal, the voltage can be measured perpendicular to the flow of current and the voltage should equal zero under no influence of a magnetic field. When a magnet field is introduced perpendicular to the flow of current a voltage is induced. If you reverse the polarity of the magnet the polarity of the induced voltage will reverse. There are distinctive features that the instrument has. The features include low current consumption, 3.5V to 24V DC operation voltage, open-Collector pre-driver, wide operating voltage range, temperature compensation, 50mA maximum sinking output current and reverse polarity protection. This is the Hall Effect named after Edwin Hall who discovered this in 1879. The principle which was used was the basic physical principle underlying the Hall Effect being Lorentz force. To generate a potential difference across the device the magnetic flux
