... forces that acted towards or away from certain points but this 'skew force' that Oersted saw went round an axis! It took Oersted four months to believe in what he saw and he finally said that it showed some 'conflicts' in the nature of electricity. The person who immediately took off from Oersted's ...

... Cooking food involves the transfer of thermal energy. In an electric stove, an electric current is directed into the element which converts the electrical energy into thermal energy. That thermal energy is transferred by conduction into a metal pot. The pot needs to increase in temperature to then t ...

... When a conductor in the form of a disc or a metallic plate as shown in Fig, swings between the poles of a magnet, electrons inside the plate experience a force [ F = -e(v ×B)] because of the motion of plate . Under the influence of this force electrons move on the path which offers minimum resistanc ...

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.
