Magnetizing an iron rod
An iron rod can be converted into a magnet by passing an electric current through an insulated coil wound around. When the current flows, the iron bar gets magnetized. One end becomes North Pole and the other the South Pole. If the direction of the current is reversed, the Nort..

A rod of length 6 m moves in such a way that its ends A and B always touches the X and Y axes. If A is at 3 m from the origin and is moving away at the rate of 0.3 m/s, then find the rate at which the area of the triangle formed by the rod with the axes is decreasing. ..
Numerical 14
A straight horizontal conducting rod of length 0.45 m and mass 60g is suspended by two vertical wires at it's ends. A current of 5.0 A is set up in the rod through the wire..
Charging by Induction
A charged plastic rod is brought close to the sphere. Free electrons in the sphere move away due to repulsion and piles up at the other end of the spher..
Demonstration of Breathing Mechanism
Take a bell jar. Towards its rounded end, fix a 'Y' shaped glass tube and on the open ends of the two branches tie a balloon each. On its open end tie a thin rubber sheet. The cavity of the bell jar acts as the thoracic cavity, the "Y" shaped tube ..
