Magnetism - Simple English Wikipedia, the free encyclopediaAn electric current makes a magnetic field. If you wrap the wire into a coil, the electrons spin around the coil and make a stronger magnetic domain. Often, these magnets work by using a coil of wire that makes a magnetic field when there is a current in it. In addition to this coil of wire, a large piece of metal, usually iron, is placed ...

Air gap [Encyclopedia Magnetica]An air gap is a practically unavoidable part of any magnetic circuit in which there is a relative movement between different parts (e.g. in motors, generators, relays, etc). Due to increased reluctance of an air gap the flux spreads into the surrounding medium causing the flux fringing effect.

Electromagnet Facts for KidsA simple electromagnet consisting of a coil of insulated wire wrapped around an iron core. A core of ferromagnetic material like iron serves to increase the magnetic field created. The strength of magnetic field generated is proportional to the amount of current through the winding.
Galvanometer - EncyclopediaThe principle on which one type of direct current galvanometer, called a movable needle galvanometer, depends for its action is that a small magnet when suspended in the centre of a coil of wire tends to set its magnetic axis in the direction of the magnetic field of the coil .
ELECTRICAL ENCYCLOPEDIA: INDUCTORS: DEFINITION AND HISTORYAn inductor is a passive electronic component that storesenergy in the form of a magnetic field. In its simplest form, an inductor consistsof a wire loop or coil. The inductance is directly proportional to the number ofturns in the coil. Inductance also depends on the radius of the coil and on the type of material around which the coil is wound.
INDUCTION COOKER:PRINCIPLES OF OPERATION - BloggerIn an induction cooker, a coil of copper wire is placed underneath the cooking pot. An alternating electric current flows through the coil, which produces an oscillating magnetic field. This field induces an electric current in the pot. Current flowing in the metal pot produces resistive heating which heats the food.
electromagnetic induction - David DarlingElectromagnetic induction is the phenomenon in which an electric field is generated in an electric circuit when the number of magnetic field lines passing through the circuit changes. Electromagnetic induction was discovered independently by Michael Faraday and Joseph Henry.The voltage induced is proportional to the rate of change of the field, and large voltages can be produced by switching ...
Electromagnetic coil - Wikipedia, the free encyclopediaAn electromagnetic coil is an electrical conductor such as a wire in the shape of a coil, spiral or helix. Electromagnetic coils are used in electrical engineering, in applications where electric currents interact with magnetic fields, in devices such as inductors, electromagnets, transformers, and sensor coils.Either an electric current is passed through the wire of the coil to generate a ...

electric motor - The Worlds of David DarlingAn electric motor is a device for converting electrical energy directly into mechanical energy. Traditional forms of electric motor are based on the force experienced by a current-carrying wire in a magnetic field.Motors can be, and sometimes are, run in reverse as a generator, to produce electrical power from mechanical power.
Excitation (magnetic) - Simple English Wikipedia, the free ...Excitation is a process to create a magnetic field from electric current.This process is used in electric machines (generators or motors) whose rotor spins in a magnetic field.This magnetic field can come from a permanent magnet or field coils. In the case of electric machine with field coils, a current must flow to the coil to generate the magnetic field, so that the field coils can act as a ...
Physics4Kids: Electricity & Magnetism: Magnetic FieldsMagnetic Field Basics Magnetic fields are different from electric fields. Although both types of fields are interconnected, they do different things. The idea of magnetic field lines and magnetic fields was first examined by Michael Faraday and later by James Clerk Maxwell.Both of these English scientists made great discoveries in the field of electromagnetism.
