From the Institute of Physics, these resources are split into topics and each topic is subdivided into a number of episodes. An episode represents a coherent section of teaching – perhaps one or two lessons. The topics covered are:

* Gravitational fields
* Electrical fields
* Coulomb's law
* Electromagnetism
* Electric motors
* Generators
* Transformers

Episode 409: Uniform Electric Fields

This learning episode, produced by the Institute of Physics, discuss the physics of the uniform electric field, such as that between two parallel charged plates. The definitions of field strength and potential lead to different results than those for the non-uniform field.

The activities in this learning...

Episode 410: Preparation for Electromagnetism Topic *suitable for home teaching*

This topic, from the Institute of Physics, develops a formal description of magnetic fields before moving on to electromagnetic forces and induction. The learning episodes follow a fairly standard approach that is similar to the order in which the topics appear in most exam specifications. The three main electrical...

Episode 411: Describing Magnetic Fields

Produced by the Institute of Physics, this learning episode uses demonstrations, experiments and questions to help students learn about electromagnetic fields. These consider their strength and direction.

The activities include:
• demonstrating the field around a permanent magnet
• field...

Episode 412: Force on a Conductor in a Magnetic Field

In this learning episode, from the Institute of Physics, students look at how a magnetic field can be quantified by measuring the force on a conductor. It illustrates how Flemming's left hand rule can be used to find the direction of the force. The activities include: 

  • investigating the relationship...
