One wire coil is connected to a radio, and another is connected to a speaker. The two coils are not connected to each other. The radio signal is transmitted through the induced magnetic field caused by the current in the wires. The signal is only received when there is a magnetic flux through the receiving coil, and thus no sound is heard when the coils are perpendicular to each other.

A solid copper pendulum is mounted between the poles of an electromagnet (solenoid). The pendulum is set into motion, and then the magnets are turned on. The magnets induce eddy currents in the copper which oppose the motion of the pendulum. The pendulum quickly slows to a stop, demonstrating an effect called eddy current braking. Eddy current brakes are widely used i

Two flexible wires are suspended vertically. The wires are conected in series or parallel to a 12V storage battery. When the wires are connected in series and power is applied they will repel each other; when they are connected in parallel they weill attract one another.
This effect is due to the magnetic fields created by the charge flowing through the wires. When the wires are in parallel, the currents in each are going in the same direction and thus attract. In series the currents are going in opposite directions and repel.

A long length of wire is suspended horizontally between the poles of a magnetron magnet. When a large current from a 12V storage battery is passed through the wire, the wire jumps out of the magnetic field. When the direction of the current is switched, the wire jumps the opposite direction.
The magnetron magnet in this demonstration was originally used in MIT's groundbreaking research developing radar during and after World War II. Microwave emitting cavity magnetrons need strong magnetic fields, which were often created by powerful permanent magnets like the one used in this demo.

A wooden ball is attached to the rim of a spinning wheel. The ball is held in place by a string. When the spring is cut, the ball flies in a straight tangent to the wheel.
In the camera's frame of reference, the ball constantly accelerates around in a circle due to the centripetal force pulling it inwards. When the string is cut, the acceleration stops, and the ball flies away in a straight tangential line. When the string is cut in the rotating frame of reference, a ficticious force (centrifugal force) accelerates the ball.

A bicycle wheel is suspended from one of end of its axie by a rope, and spun up by hand. The wheel's axle is then placed horizontally and the free end of the axle processes about the supported end.
The gyroscope seems to defy gravity because the torque created by the spinning wheel counteracts the torque due to gravity. Gyroscopes have been used through history for varied uses such as stabilizing spacecraft or for guidance systems on ships and missiles.

A string carrying two weights is hung over a low friction bearing mounted pulley. The weights have slightly different masses, causing a uniform acceleration. When the time it takes the weights to move 1 meter is timed, we can calculate the acceleration of the system due to gravity. Because of the low amount of friction in the system, this value is very close to the theoretical value.

Kalaripayattu - The Orient's treasure trove, a gift to the modern world and the mother of all martial arts. Legend traces the 3000-year-old art form to Sage Parasurama- the master of all martial art forms and credited to be the re-claimer of Kerala from the Arabian Sea. Kalaripayattu originated in ancient South India. Kung- fu, popularized by the monks of the Shoaling Temple traces its ancestry to Bodhi Dharma - an Indian Buddhist monk and Kalaripayattu master.
Crafted in ancient South India drawing inspiration from the raw power and sinuous strength of the majestic animal forms - Lion, Tiger, Elephant, Wild Boar, Snake, and Crocodile ........ Kalaripayattu laid do
