Fields: Magnetic Field
Unit 3 Fields: The Magnetic Field
This Area of Study looks at three fields: Gravitational, Electric and Magnetic. Resources for the other fields are available at Gravitational Field and Electric Field.

'Teaching Advanced Physics' is a UK resource for teachers new to teaching physics. It assumes only a limited access to equipment, resources, and advice from experienced colleagues. The section on Fields covers Gravitational and Electrical Fields and Electromagnetism. It consists of 16 episodes, each of which is for one or two 60 min lessons. Content of each episode is a lesson plan with a description of the content covered, with points to emphasise in discussion, along with activity or question sheets for the students.
- VCE Physics: Electric Power, 1994, 2nd edn, National Electricity.
It is recommended that teachers should view any video before purchase.
- Marcom Projects: Electricity & Magnetism & Electromagnetic devices, Electric Motors & Electric Generators, Power Transmission & Power Consumption
Possible practical activities include:
- Practical Physics by Gardiner & White: i) Magnetic field of a current loop, ii) Magnetic field of a solenoid
- Physics Experiments by McKittrick: i) Magnetic force on moving charges
Worksheets for experiments for Unit 3 Magnetic Fields and Electrical Energy Areas of Study.
Describes the magnetic force on moving charges and goes on to look at the effect of the Earth's magnetic field on charges from the Sun and at the Hall effect, which gives us insight into the nature of electric currents as well as many practical applications.
Summaries of selected articles from the 'News from the Web' section of the Vicphysics Newsletter. Each summary as a link to the full article. The articles can be used to add context to class discussion or to display within the classroom.

A very comprehensive website on motors, generators and transformers featuring many effective animations by the University of New South Wales.
The IEEE Global History Network is a wiki-based platform dedicated to preserving and promoting the history of innovation in the fields of electrical engineering and its allied fields. There is considerable educational material but much is related to history, but the site is very comprehensive.
The applet by Walter Fendt shows a U shaped wire in the magnetic field of a horseshoe magnet. You are able to turn on a current and see the wire move. You can reverse the magnet and the direction of the current. The display shows the direction of the current, the magnetic field and the force.
Applet by Walter Fendt. The display shows a coil rotating slowly in magnetic field. The coil is linked to a battery through a commutator. You can reverse the direction of the current and increase the speed of rotation, you also can decide to show the directions of the magnetic field, the current and the direction of the magnetic force called the Lorentz force.
An applet by Walter Fendt. Use the muse to move a compass around a bar magnet.
An applet by Walter Fendt. Use the muse to move a compass around a current carrying wire.
This applet is by Surendranath. The strength of the field and the speed of the particle can be changed.
