ELECTROMAGNETIC INDUCTION Electromagnetic induction is the production of an electromotive force across a conductor when it is exposed to a varying magnetic field. It is described mathematically by Faraday’s law of induction‚ named after Michael Faraday who is generally credited with the discovery of induction in 1831. Electromagnetic induction was discovered independently by Michael Faraday and Joseph Henry in 1831; however‚ Faraday was the first to publish the results of his experiments.[4][5] In

Electrical technology – assignment 4 Properties of electrical materials and Effective use of technology P.5. Describe the properties and a typical application of a solid and a liquid or gas electrical conductor. A conductor is a material that allows free movement of electrons and therefore allows easy flow of electricity. Most conductors are metals. A common metal used as a conductor in electrical technology is aluminium. It is used quite a lot as it cheap‚ lightweight and in abundance compared

Basics of Magnetism by Ron Kurtus (revised 29 January 2013) Magnetism is a force of attraction or replusion that acts at a distance. It is due to a magnetic field‚ which is caused by moving electrically charged particles. It is also inherent in magnetic objects such as a magnet. A magnet is an object that exhibits a strong magnetic field and will attract materials like iron to it. Magnets have two poles‚ called the north (N) and south (S) poles. Two magnets will be attacted by their opposite poles

has been modified to function as an amplidyne. INTRODUCTION A generator is a machine that converts mechanical energy into electrical energy by using the principle of magnetic induction. This principle is explained as follows: Whenever a conductor is moved within a magnetic field in such a way that the conductor cuts across magnetic lines of flux‚ voltage is generated in the conductor. 1-1 The AMOUNT of voltage generated depends on

Motors use the effect of forces on current-carrying conductors in magnetic fields Discuss the effect on the magnitude of the force on a current-carrying conductor of variations in: The strength of the magnetic field in which it is located • The magnitude of the force is proportional to the magnetic field strength. Thus‚ an increase in magnetic field strength will cause an increase in the force on the wire and a decrease in magnetic field strength will cause a decrease in force on the wire.

of degrees that it was designed for when each pulse is delivered‚ you can control the pulses that are sent and control the positioning and speed. The rotor of the motor produces torque from the interaction between the magnetic field in the stator and rotor. The strength of the magnetic fields is proportional to the amount of current sent to the stator and the number of turns in the windings. The stepper motor uses the theory of operation for magnets to make the motor shaft turn a precise distance when
