Hall, <\/b><span style=\"font-weight: 400;\">who first<\/span><b> introduced the theory<\/b><span style=\"font-weight: 400;\"> to the world in <\/span><b>1879<\/b><span style=\"font-weight: 400;\">.\u00a0<\/span><\/li>\n<li><span style=\"font-weight: 400;\">Hall discovered that when a <\/span><b>conductor or semiconductor with current flowing in one direction<\/b><span style=\"font-weight: 400;\"> was <\/span><b>introduced to a perpendicular magnetic field, a voltage could be measured <\/b><span style=\"font-weight: 400;\">at right angles to the current path; this measurable voltage is the<\/span><b> Hall Effect.\u00a0<\/b><\/li>\n<li><b>How does it work?<\/b>\n<ul>\n<li><span style=\"font-weight: 400;\">The Hall effect takes place when you set <\/span><b>current flowing through a conductor, <\/b><span style=\"font-weight: 400;\">which is a material such as copper or silver that <\/span><b>permits electrons to flow freely <\/b><span style=\"font-weight: 400;\">across the entire surface area.\u00a0<\/span><\/li>\n<li><span style=\"font-weight: 400;\">The <\/span><b>electrons <\/b><span style=\"font-weight: 400;\">begin to<\/span><b> flow in a straight line from one side <\/b><span style=\"font-weight: 400;\">of the conductor<\/span><b> to the other.<\/b><\/li>\n<li><b>I<\/b><span style=\"font-weight: 400;\">f you were to introduce <\/span><b>a magnetic field near the conductor, <\/b><span style=\"font-weight: 400;\">it would <\/span><b>disturb <\/b><span style=\"font-weight: 400;\">the <\/span><b>flow of the electrons due to the force applied.\u00a0<\/b><\/li>\n<li><span style=\"font-weight: 400;\">This is called <\/span><b>Lorentz force,<\/b><span style=\"font-weight: 400;\"> which is the <\/span><b>force on a charged particle due to electric and magnetic fields.\u00a0<\/b><\/li>\n<li><span style=\"font-weight: 400;\">The<\/span><b> magnet\u2019s north pole pulls the negative electrons to one side<\/b><span style=\"font-weight: 400;\"> of the conductor and<\/span><b> deflects the positive electrons to the other side <\/b><span style=\"font-weight: 400;\">of the conductor.\u00a0<\/span><\/li>\n<li><span style=\"font-weight: 400;\">If you then put a voltage tester between the two sides, you will be given a <\/span><b>voltage reading<\/b><span style=\"font-weight: 400;\"> because there is <\/span><b>current between the positive and negative electrons;<\/b><span style=\"font-weight: 400;\"> by retrieving this measurable voltage, you are putting the Hall Effect principle into practice.<\/span><\/li>\n<li><span style=\"font-weight: 400;\">\u00a0<\/span><b>In a semiconductor<\/b><span style=\"font-weight: 400;\"> such as silicon or germanium, the <\/span><b>drift velocity of electrons <\/b><span style=\"font-weight: 400;\">is a<\/span><b> lot quicker<\/b><span style=\"font-weight: 400;\"> due to the material used.\u00a0<\/span><\/li>\n<li><span style=\"font-weight: 400;\">This<\/span><b> results in a stronger Hall effect <\/b><span style=\"font-weight: 400;\">which corresponds to a <\/span><b>larger voltage reading <\/b><span style=\"font-weight: 400;\">being detected and therefore a more precise reading being taken.\u00a0<\/span><\/li>\n<\/ul>\n<\/li>\n<li><span style=\"font-weight: 400;\">The Hall effect is<\/span><b> used in several <\/b><span style=\"font-weight: 400;\">different<\/span><b> products, such as sensors, joysticks, and switches.\u00a0\u00a0<\/b><\/li>\n<li><span style=\"font-weight: 400;\">A <\/span><b>Hall effect sensor<\/b><span style=\"font-weight: 400;\"> is a device to <\/span><b>measure the magnitude of a magnetic field.<\/b><span style=\"font-weight: 400;\">\u00a0<\/span>\n<ul>\n<li><span style=\"font-weight: 400;\">Its <\/span><b>output voltage <\/b><span style=\"font-weight: 400;\">is <\/span><b>directly proportional to the magnetic field strength<\/b><span style=\"font-weight: 400;\"> through it.\u00a0<\/span><\/li>\n<li><span style=\"font-weight: 400;\">Hall effect sensors are<\/span><b> used for proximity sensing, positioning, speed detection,<\/b><span style=\"font-weight: 400;\"> and current sensing applications.\u00a0<\/span><\/li>\n<\/ul>\n<\/li>\n<\/ul>\n<h2><b>Recent Findings<\/b><\/h2>\n<ul>\n<li><span style=\"font-weight: 400;\">For a long time, people thought the Hall effect only worked when the magnetic field was applied perpendicular to the plane of the film.\u00a0<\/span><\/li>\n<li><span style=\"font-weight: 400;\">The recent findings show that a <\/span><b>Hall response tied to magnetization can occur in more than one direction.\u00a0<\/b><\/li>\n<li><span style=\"font-weight: 400;\">That gives physicists a new way to investigate multidimensional magnetic and topological structures in condensed matter systems. <\/span><\/li>\n<\/ul>\n<p><b>News: <\/b><a
