Magnetism: Magnetism is physical phenomenon that is mediated by magnetic fields. Materials that allow electricity to pass through them are called conductors. Freely browse and use OCW materials at your own pace. Some items such as iron and nickel get attracted to magnets and are called magnetic materials. Revision Notes on Current Electricity:-Current:- Current strength, in a conductor, is defined as the rate of flow of charge across any cross section of the conductor.I= q/t = ne/t. Uses: While using electricity, we are basically converting electrical energy to various forms according to our need. Learn the generation of current electricity and more. Welcome! Each electron is surrounded by a force called an electric field.When an electron moves, it creates a second field – a magnetic field.When electrons are made to flow in a current through a conductor, such as a piece of metal or a coil of wire, the conductor becomes a temporary magnet – an electromagnet. I dt. A magnet attracts the magnetic materials. Learn about how consumption of electricity takes place in households. MIT OpenCourseWare is a free & open publication of material from thousands of MIT courses, covering the entire MIT curriculum.. No enrollment or registration. For non-uniform flow, I= dq/dt.
