Electric Generator

An electric  generator works on the principle of electromagnetic induction. When a coil is rotated in the presence of a strong magnet, electricity is produced.See the video below for demonstrating a simple electric generator.

Collisions and Principle of Conservation of Momentum – Weblinks

According to the principle of conservation of momentum, the total momentum of a system of particles remains constant provided no external force acts on it. Principle of conservation of momentum is one of the fundamental concepts of Physics.  


A moving coil galvanometer is an instrument used for detection and measurement of small electric currents. Principle A current carrying conductor placed in a magnetic field experiences a torque. See Animation

Cyclotron Animation

A cyclotron is device by which positively charged particle can be accelerated and the desired nuclear reaction can be brought about. Principle A positively charged particle can be accelerated to high energy with the help of an oscillating electric field, by making it cross the same electric field time and again with the use of … Continue reading Cyclotron Animation
