This is a site which is designed to reinforce the 3 key principles in Electromagnetism

1. A current carrying conductor in a magnetic field experiences a force.
2. A coil that is in the presence of a changing magnetic field will have an EMF induced in it, this induced EMF will drive an induced current
3. When a current flows through a wire, a magnetic field will be created concentric with the conductor. An iron core placed at the centre of the core will become magetised when current flows through the coil, and demagnetised when the current stops flowing.
