How to Make a Simple Electric Motor Energy comes in many forms. Electric energy can be converted into useful work‚ or mechanical energy‚ by machines called electric motors. Electric motors work due to electromagnetic interactions: the interaction ofcurrent (the flow of electrons) and a magnetic field. Problem Find out how to make a simple electric motor. Materials Needed D battery Insulated 22G wire 2 large-eyed‚ long‚ metal sewing needles (the eyes must be large enough to fit the wire through)

One fine day‚ as I was going through the library shelf‚ I noticed a book named “the Steve Jobs way” saying iLeadership for a new generation. As I started imagining about leadership‚ I came across a most important thing called positive change. To me‚ positive change means transition and improvement in one’s own thoughts‚ ideas‚ acts and applying those in everyday life to bring the society together for a known cause. When the society gets together‚ working towards one direction‚ a certain positive

Sakib Khan Electric Eels – Physics The animal that is usually known as electric eel is in fact not really an eel but a freshwater species related more to the carp family or catfish family. These unique freshwater predators got their name from the immense electrical charge that they can easily generate to stun or even kill their preys and dissuade predators. Electric eels can grow extremely large which usually can reach as high as 8 foot long and weigh a great amount of 45lbs. In addition to this
