Definition of a magnet?
A magnet is a material or object that produces a magnetic field.
What is the purpose of the coil in a speaker?
The coil produces a magnetic field. When power is applied to the wire in the coil, the result is a magnetic charge. This magnetic charge is part of how the speaker produces sound.
How electric current have magnetic effect?
The magnetic force acts only on moving electric charges; A constant electric current produces an unchanging magnetic field and a changing electric current produces a changing magnetic field.
Is a magnet a conductor?
A magnet will conduct electricity.
Why generator produces only AC?
A generator produces electricity by moving wires through a magnetic field. The direction of the induced current is dependent upon the direction in which the wire crosses the magnetic field. In a generator the magnetic field is usually fixed - and the wires are spinning through it. So: Visualize a horizontal magnetic field. The axis of rotation of the wires is perpendicular to the field. Any given wire will be cutting up through the field at a given point... then, 180º later will be cutting down through the same field. The direction of the induced current will reverse with each half-rotation because the wire will be moving in the opposite direction relative to the magnetic field. (In the USA the generators produce "60 cycle" current. That tells you that the generators are turning their wires (coils) at 60 revolutions per second.) Richard yeaa buddie...Lickety splyt
What is the difference between a magnet and magnetic material?
magnet attracks magnegtic material but magnetic meaterial does not atterck or repel\ magnet attracks magnegtic material but magnetic meaterial does not atterck or repel\The magnetic material is any material in which for a short time the domains are alligned in same direction.This material can be anything like iron,etc.The magnet is a steel in which the domains are permanently arranged in same direction by rubbing method.
Definition of a magnet?
A magnet is a material or object that produces a magnetic field.
An electric current produces?
Produces magnetic fields, that are used in generators, inductors and motors. The magnetic field at any given point is specified by both a magnitude and a direction.
Coil made up of which material produces highest magnetic flux?
I think cooper coil
What is definition of paramagnetic and dimagnetic materials?
A dimagnetic material produces a magnetic field that opposes an external field. A paramagnetic materia, on the other hand, produces a magnetic field that increases an external field. Dimagnetism and paramagnetism are induced when an object is placed in a magnetic field.
Does an electric current produces a magnetic field?
yes*edit: don't confuse moving with changing. A change in magnetic field strength/direction will induce an electric current.
What are the physics behind dropping a magnet down a metal pipe?
As a magnetic field passes by a ferrous material an electric current is created locally in that material, in this case the pipe. Anytime an electric current is produced that changes with time, a magnetic field is generated. The magnetic field that the pipe produces creates a force in the opposite direction of gravity. This magnetic field created by the pipe affects the magnet falling and creates a breaking force. This whole thing is refereed to as Eddy Currents.
Does lightning produces magnetic field?
Yes, The movement of electrical charges produces a magnetic field
Which layer of the earth produces its magnetic field?
The earth's outer core produces the magnetic field.
How does magnitiom work?
A magnet is any material or object that produces a magnetic field. This magnetic field is responsible for the property of a magnet: a force that pulls on other ferromagnetic materials and attracts or repels other magnets.
What is an electrical current that produces a magnetic field?
The deflection of a magnetic compass in the presence of an electric current, is evidence that an electric current produces a magnetic field.
What is evidence that an electrical current produces a magnetic field?
The deflection of a magnetic compass in the presence of an electric current, is evidence that an electric current produces a magnetic field.
