Electromagnetic Induction
What happens when you move a magnet into a coil of wire? What other methods can we produce a changing magnetic field and hence, induce an emf? What factors affect the emf induced? Learn about the answers to these questions plus a lot more.

Electromagnetism and Force on a Current-carrying Wire
What is an electromagnet? What factors affect its magnetic strength? What are its uses? What happens to a current-carrying wire when placed in a magnetic field? Know the answers to these questions and more. Be delighted to use your hands to understand the other concepts as well. Play with the simulation and enjoy electromagnetism.

Electrical Quantities
Current, voltage and resistance --> three of the important quantities in terms of electricity. Know the different types of current, different types of circuits as well as the important elements in a simple circuit. Then, recall some properties of series and parallel circuits and the interesting story behind ohm.

Electrical Charge
The ancient Greeks had fun with their new-found magical powers, which we now downgrade to merely electrostatic. Understand the concept of electric charge and why charges can attract or repel each other at a distance. (We definitely had fun with the hands-on demonstrations of my own magical powers, didn't we?)
Relive the fun of doing electric hockey with the simulation file below.
