Faraday's law of electromagnetic induction states that an electromotive force is induced in a loop of copper wire when there is a change of magnetic flux linking the loop. According to this, the induced EMF is equal to the negative of the rate of change of flux. This principle can be tested out with an oscillating magnet that goes through a loop of wire fashioned into a solenoid. This is the case being used in the present experiment. The collected data can be used to quantitatively verify Faraday's law of electromagnetic induction.

Equilibrium in rotational motion is a tricky concept. This experiment helps you explore precisely that. It also helps you learn why is the earth bulged at the equator and squished at the poles. Rotating a stone attached to the end of a string ultimately lifts it. See this in action, and that too quantitatively.

This experiment uses a conical pendulum to familiarize the experimenter with dynamic equilibrium in rotational motion. In this investigation, we identify the free body diagram of a horizontally whirling object and see how the object lifts as its speed goes up. The lift apparently defies the downward pull of gravity but we see how an angular balance of forces allows the object to swirl at a certain lift angle. As the speed of the object changes, the forces adapt and preserve the delicate balance.

PhysHivolt a DC high voltage supply with a user adjustable range of 0-30kV. It is designed to be used in electro-spinning, electro-spraying and other application where a static voltage or a low power source is required. The supply has been tuned for minimal electromagnetic noise, resistance against short circuit and tolerance against overloading.

Almost all of the known physical systems are essentially nonlinear. Yet, for simplicity, they can be treated as linear systems within some operating constraints. The magnetic pendulum is one such system. It is essentially a nonlinear system. So, it can help us to look into nonlinear phenomena such as chaos.
