This is a teacher or student controlled, realistic 3d simulation of a flux linkage experiment using a signal generator, search coil and oscilloscope.

This experiment establishes the relationship between the induced voltage in a coil when at various angles to another coil. It uses audio signals from a signal generator to vary the input voltage. By measuring the voltage induced in the search coilusing an oscilloscope, and varying the angle of the search coil, the relationship between the induced voltage and the angle of the search coil can be established

The user has control over the angle of the search coil, the amplitude and frequency of the signal from the signal generator, the various controls of the oscilloscope which include the amplitude sensitivity, the time frame, and the various cursor controls. The user is free to move anywhere within the laboratory in order to interact with the apparatus.

Instructions on performing the experiment and controlling the simulation are within the simulation.

There’s a video of using this simulation here: https://youtu.be/KdXWmYYLh5c

The simulation is perfect for demonstrating this experiment in front of the class but can also be used by students in a variety of ways:

Directly to prepare for a laboratory experiment by familiarising them with the equipment to be used and the methodology of the experiment.

As revision for an experiment that has previously been performed in the laboratory.

For home-learning where there is no access to a laboratory.

To make up for an experiment missed due to sickness.

As a personal experience of an experiment normally only performed by the teacher in front of the class.
Download contains full instructions on using the simulation, a PowerPoint giving full instructons including a video , background on the Physics and link to the simulation.

The Virtual Physics Laboratory of which this simulation is a part, has the Association for Science Education’s Green Tick of Approval. More information can be found on our website at www.virtual-science.co.uk.

I’ve found your software very useful when a concept comes up with pupils and I have to demonstrate something really quickly without having the time to set up a formal experiment for them. The graphics are great and I really like the ability to move around the classroom and observe the experiment from different aspects. I am far more likely to go to one of your interactive experiments if it’s demonstrating something that we don’t have equipment for.“
