Just like a normal magnet has got a magnetic field, electromagnets also have got a sort of these poles determine if it will repel the other magnets and magnetic substances or will attract them. Unlike permanent magnets, the strength of an electromagnet can be conveniently changed by varying the amount of electric current that goes through it.
You may never see some electromagnets, but they often lie hidden in many electronic products you use. May occur if stronger magnetic fields within the coil. An electromagnet is a magnet that consists of a piece of iron or steel surrounded by a coil. An electromagnet works on the principle that an electric current not only allows electrons to flow in a circuit, but also generates a small magnetic field. An electromagnet is a coil of wire with an electric current flowing through it.

An electromagnet is a type of magnet in which the magnetic field is produced by an electric current. The phenomenon by which magnetism is produced by the effect of electric current is called electromagnetism.if electric current is passed in a simple magnet wound with the coil of insulated wire and magnetic field is produced the magnet formed by this process is called electromagnet. A solenoid would be a closed toroid.
When a wire that's near to a changing magnetic field produces electric current, this phenomenon is called induction. Unlike a permanent magnet, the strength of an electromagnet can easily be changed by changing the amount of electric current that flows through it. The electromagnet is a temporary magnet which can be magnetized or demagnetized in a very short time as per our requirements. Electromagnets are found in motors, tape decks, hard drives, vcrs and tons of other devices. Electromagnets are very useful where the changing of poles and discontinuation of the magnetic field is necessary.

They are used in cell phones that work on the interaction between the phone signals and magnetic pulses produced by an electromagnet inside the phone. As the flow of electrical current through a conductor produces a magnetic. An electromagnet is a device which creates a magnetic field on demand when excited with electrical current. The electromagnet is a simple piece of metal wire wound in a coil. These magnets are formed by the wire when it mostly used conductor for the electromagnet is iron because it concentrates the flux produced by the current at the center and make high power. In the simplest form, an electromagnet consists simply of a soft iron core around which a large number of turns of insulated wire are wound. The magnetic field disappears when the current is turned off. A solenoid would be a closed toroid. An electromagnet is a coil of wire with an electric current flowing through it. Electromagnets are used in devices such as electric bells, and door locks that can be controlled.
