Frank ICSE Solutions for Class 9 Physics – Electricity and Magnetism: Current Electricity. Home Class 8 th Class 8 th, Gereral Science,4.Current Electricity and Magnetism Godavari Zore August 16, 2020 0 Comments. Items that do not get attracted to magnets are called non-magnetic. 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. Magnetic lines of force never intersect each other. MCQs. https://examtimequiz.com/physics-mcq-on-current-electricity Video Lesson. 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.
