Electro Magnet (2)

An electromagnet consists of a coil of wire wrapped on an iron core and generates magnetic flux when electricity is allowed to pass through it. The coil forms the shape of the tube which is called as solenoid. If ferromagnetic material is placed inside the coil much stronger magnetic field can be created. Much stronger magnetic fields can be produced if a "core" of paramagnetic or ferromagnetic material (commonly iron) is placed inside the coil.

Applications
Electro magnets have wide industrial and non industrial applications which are as follows:

• Circuit-breakers
• Cars, they are used in electromagnet brakes and clutches.
• Electric motors too are electromagnets.
• Electromagnets are used in solenoid valves and door locks.
• They are also used in a rotary electric motor to produce a revolving magnetic field that spins the rotor.
• In linear motors, they produce a moving magnetic field that thrusts the projectile.
• Electromagnets are used in particle accelerators.
• Nuclear magnetic resonance studies
• Magnetic susceptibility measurements
• Hall effect studies
• Magnetic hysteresis studies
• It is also used in electric motors
• Doorbells
• Electric generators
• Loudspeakers
• Television receivers
• Atomic particle accelerator
