When a pice of magnet shuttles through a loop of conductor (copper wire) it induces electric energy in the conductor, this is known as induction. When alternating current (AC) or interrupted DC current applied to the primary winding of a transformer, the magnetic flux cutting through the secondary known as conduction produces electric power in the secondary. The ratio of power gained or lost in the secondary winding depends on the ratio of turns of conductor between primary and secondary. Newaz.

Any conductor carrying an electric current induces a magnetic field. If the conductor is wrapped around an iron core, the magnetic field produced can be used for many uses. …Most people have seen scrap-yard magnets used for picking up iron and steel scrap. Electromagnets are also used as electrical relays, speakers, mechanical movements, and metal separators in industry. There are thousands of other uses for this very useful device. A simple electromagnet is constructed by winding a wire around a cylinder (e.g., empty thread spool) and attaching the ends of the wire to the poles (+ and -) of a battery. An electromagnet is a coil of wire wrapped around a metal core several times. The individual magnetic fields of the individual wires reinforce and strengthen to form one large magnetic field.
Electromagnetism is the "effect" of the electromagnetic force, which is one of the four fundamental forces in the universe. Electromagnetism speaks to electric fields and the …relationship between magnetic fields and moving electric fields. Electromagnetism is the force that causes the interaction between electrically charged particles, and is responsible for practically all the phenomena observed in daily life, except gravity. Electricity and magnetism are the two obvious examples. The chemical bonds holding molecules together are electromagnetic. Light is electromagnetic radiation. The light need not be visible light. Heat, infrared radiation, UV (ultraviolet radiation), gamma rays, microwaves, radio waves--all of these are examples of light. The photon is the gauge boson which mediates the electromagnetic force. Refer to the link below to read more about the electromagnetic force. Magnetism induced on a ferric material form the alignment of electrons caused by a electric field.
Electromagnetic energy refers to the energy that comes from electromagnetic radiation. This radiation is composed of waves that move at the speed of light in a way… that is suggestive of both waves and particles.
An electromagnet is a magnet that runs on electricity. Unlike a permanent magnet, the strength of an electromagnet can easily be changed by changing the amount of electric cur…rent that flows through it. The poles of an electromagnet can even be reversed by reversing the flow of electricity. An electromagnet works because an electric current produces a magnetic field. The magnetic field produced by an electric current forms circles around the electric current.
It is the joining of electricity and magnetic field, it is the study if the interaction between the two.
An electromagnet is a controllable magnet. It can be switched on and off. This is useful for all kinds of applications. The magnet can attract an armature, causing physical …movement. This can be used to make a heavy duty switch (as in relays and contactors ), or used to unlatch doors and locks etc. The biggest and most obvious use in industry, is to lift piles of scrap iron using a crane. The magnet is energized when lifting and switched off when you want the scrap to drop.
Quite a lot of things, speakers, telephones, tatoo guns, certain componets in computers, (fans) industrinal -to pick up cars, scrap, ect, mri machines, and a hole host of othe…r things.
An electromagnet is a magnet carrying an electric current. This can be useful for many things. eg, door bells.
Electromagnetics is the field of study of the combination ofelectricity and magnetism.
It is the ability of the atom in covalent molecule to attract the electrons of the bond towards itself.
Many things. Particle accelerators, Rail Guns, motors, generators and MAGLEV trains.
An electromagnet converts electric current into a magnetic field. They are useful when the magnet should be able to be controlled, rather than a permanent magnet.
A lot of things like a blender and a speaker and so many other things i can't think of right now :)
First let's take a look at an electromagnet. Some are powered by a direct current or (d.c.) A solenoid is a "sucking magnet," put power to your coil and iron inside will be pu…lled rapidly inside. Another interesting property is easily demonstrated with a coil wire and a strong magnet. Connect the leads of the coil to a meter that will measure micro amperes. Insert a steel nail through the coil and stroke the magnet back and forth across the coil. The meter will indicate a few micro amperes with each stroke. The direction of the current, (polarity) will reverse on the back strokes. What an electromagnet can do is produce a potential difference of up to several volts. When the electromagnet is set up in a fashion that resembles a small electric motor attach a propeller to the shaft allowing the wind to turn the coil inside of the magnet housing thus generating voltage.
