Electronics and technology has opened new visions for us. But rarely do we find ourselves interested in the basics of the working mechanism of a device. We all have studied about magnetism in schools and colleges but seldom did we realize their role in today’s world of electronics and new generation of technology. Like magnets, there are also Electromagnet which are different type of magnets forming a magnetic field with the flow of electricity. The magnetic effect disappears when the flow of electricity is stopped. Their principle of operations reads simple but such simple aspects forms the foundation of much electronic equipment like generators, hard-disks, MRI scan machines and lot others. The main advantage of using electromagnets over normal magnets is that the magnetic field can be manipulated by controlling the flow of electricity.

The most wonderful invention using electromagnetism technology is the Maglev train which move by levitating itself above the rail tracks. These trains offer faster transportation, less vibration and are much more convenient for people. Moreover, such a mechanism of transport is also environment friendly as no toxic gases are evolved in atmosphere and the train operates on the magnetic field produced by electromagnets. Not only in transportation, have electromagnets also proved their excellence in development of medical equipment like magnetic resonance imaging (MRI) scan machines..

Hard disk drives in your computer to video filming tapes are also miracles of Electromagnet. Data storage capacity of disks and associated faster recording speed has been possible only for them. Electromagnets are used in particle accelerator which is an important device for scientists where they are used to accelerate the particle speed in a non-liner direction. The wonders of electromagnets are many and if we start, probably we will not end up..
