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)

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
