A is the North Pole and B is the South Pole. 8-2 Introduction to Magnetic Fields 8.1 Introduction We have seen that a charged object produces an electric field E G at all points in space. 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. Magnetic force of lines are continuous curve because magnetic lines of force starts at north pole and ends at south pole externally whereas south pole to north pole internally. Properties of magnets. Every material is influenced to some extent by a magnetic field. MAGNETISM AND ELECTRICITY.

The focus is on While using electricity, we are basically converting electrical energy to various forms according to our need. Materials that allow electricity to pass through them are called conductors. Angle of dip is zero at magnetic equator because at equator poles of magnetic needle is equally and oppositely attracted by the magnetic poles of earth due to which dip needle remains parallel by making 0 0 with the horizontal axis.. b. Some items such as iron and nickel get attracted to magnets and are called magnetic materials. Or, q = ? 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. Magnetism: Magnetism is physical phenomenon that is mediated by magnetic fields. In a similar manner, a bar magnet is a source of a magnetic field B G. This can be readily demonstrated by moving a compass near the magnet. For non-uniform flow, I= dq/dt. This freshman-level course is the second semester of introductory physics.
