Electromagnetism

 

In 1820, Oersted connected a battery to a wire that ran near a magnetic compass. The compass needle swung around, and he realized that the current was producing magnetism.

When Oersted discovered that electricity produced magnetism, Faraday wondered if magnetism could produce electricity. In 1831, Faraday pushed a magnet into a coil of wire and found that a moving magnet created a current.

Thus, Electromagnetism is:

‘A TWO-WAY LINK BETWEEN ELECTRICITY AND MAGNETISM’

An electric current creates a magnetic field, and a magnetic field, when it changes, creates a voltage.

The principal of Electromagnetism forms the basis of many everyday objects including doorbells, telephones, radios, headphones, burglar alarms, in scrap yards and so on.

We at Radical assure a crystal clear understanding of this phenomenon with our fun hands-on equipments, designed principally to evoke the interest of the students.
