World's First Electric Motor !!

Just a year after electromagnetism was discovered, Michael Faraday figured out how to turn it into motion, thus creating the world’s first motor. Though the work is done by it is really less, but you can imagine the excitement of the scientist when it had started moving. It was a great leap for humankind and led to the more sophisticated motors of today.

For his motor, Faraday first created a circuit comprised of a wire, a battery, and a vessel of mercury (a very good conductor). Here, we have used salt+water instead of mercury. The wire was arranged so that one end hung free in the mercury vessel. When current is passed through the circuit (9V), it generated a circular magnetic field around the wire. The wire’s magnetic field interacted with the magnetic field of a permanent magnet fixed to the center of the dish. Two forces interacted to create motion – and change the course of history!

About Us

We came into being in order to nurture a scientific temperament among adults and children alike. Our journey began from an empty 400 sq feet room, and today, 2 years later, we have 3 rooms full of 450+ unique STEM models and activities, created by us. Having conducted 70+ STEM and hands-on learning workshops for over 6,000 teachers & engineering college professors and 50,000 students from all across the country - our mission is to bring back the gleam in their eyes!
