Faraday's Law

Faraday's law of induction describes a basic law of electromagnetism, which is involved in the working of transformers, inductors, and many forms of electrical generators. The law states that the induced electromotive force (EMF) in any closed circuit is equal to the time rate of change of the magnetic flux through the circuit.

In this Adaptive Tutorial, a single circular coil is oriented in a uniform magnetic field where the coil's angle and intensity of the magnetic field are adjustable. A reading of the magnetic flux measured for the setup is given to test the concepts of Faraday's Law.

Circular Motion

The Circular Motion tutorial is designed as the first tutorial in a series for teaching the fundamentals of waves.

Period and frequency are fundamental concepts for studying cyclical processes such as rotation, oscillation, and waves - the basis for investigating vibration, acoustics, optics, electromagnetism as well as atomic physics.

In this Adaptive Tutorial, you will investigate how a cyclical system behaves, relating period to frequency. The apparatus in question is a green dot rotating about a circular path. The stopwatch provided allows you to measure time in the system by clicking the "Start" and "Stop" buttons, and the time measured is recorded automatically into the spreadsheet provided.

Mass On Spring

The Mass On Spring tutorial is the second tutorial in a series for teaching the fundamentals of waves.

In this Adaptive Tutorial, you will learn how a mass on a spring system behaves, relating the stiffness of the spring and mass of the block to its period, amplitude and velocity.

In the first part of the tutorial, the apparatus is a mass fixed on a spring. Some questions establish theory related to such a system, while other questions require you to interact by dragging the mass (and release it) while adjusting toggles in order to solve these problems.

In the second part of the tutorial, a bullet is fired and hits the mass that is attached to the massless spring causing the system to oscillate. When the bullet hits the mass on spring, it can either deflect completely, or embeds completely with the mass on spring. With the bullet's velocity and mass given, this experiement allows the user to learn about the conservation of energy, and calculate the displacement and velocity of the setup.
