Fleming鈥檚 left hand rule

Description

During a Mexican wrestling show Ayla and Aiysha are keen to see a rare wrestling move being performed. Ayla鈥檚 phone application Ada, misinterprets the girl鈥檚 conversation and begins to explain how electricity is generated. Ada discusses how a generator generates electricity using an inductor. Key factors of inductors are also discussed with the focus being on magnetic fields, currents and movement; Fleming鈥檚 left hand rule is used here to explain how altering one factor effects the other two factors.

Classroom Ideas

Use a lab sized generator to produce an electrical current by using the animation to plan the experiment. Watch the animation and describe a simple way to generate electricity. Use the animation to write a short poem to remember how electricity is generated. Describe the operation of transformers and why they make the national grid more efficient. After watching the animation, name all factors that contribute to an inductor.
