Episode 413: The Force on a Moving Charge
This learning episode, from the Institute of Physics, help students extend the idea of a magnetic force on a current to consider moving charges.
A range of activities are suggested and these include:
• demonstrating the deviation of an electron beam
• investigating the relationship between...
Episode 414: Electromagnetic Induction
In these activities, from the Institute of Physics, students investigate electromagnetic induction. The learning episode develops a picture of induction as the cutting of lines of flux by a conductor, which leads to an induced electromotive force (emf) or current. The activities in this learning episode include:...
Episode 415: Electric Motors
Some common electromagnetic machines include motors, generators and transformers. In this learning episode, from the Institute of Physics, all three are described. Students discuss torque, back electromotive force (emf) and power. The activities include looking at:
- a model motor
- motor torque...
Episode 416: Generators and Transformers
Produced by the Institute of Physics, these discussions and demonstrations show that in a generator, motion of a conductor in a magnetic field induces an electromotive force (emf). In a transformer, it is the changing field that induces an emf in a fixed conductor.
The activities in this learning episode...
