Lessons designed to build upon students knowledge of current and magnetic fields. Includes methods of increasing the rate of induction and Flemming’s right hand rule - contains practice questions for students.
Ideal for AQA GCSE (9-1) P7, Cambridge iGCSE P9 and more
Developing: Show understanding that a conductor moving across a magnetic field or a changing magnetic field linking with a conductor can induce an e.m.f. in the conductor.
Secure: State the factors affecting the size of an induced e.m.f.
Exceeding: Describe an experiment to demonstrate electromagnetic induction.
Developing: Recall that an induced current always flows in a direction such that it opposes the change which produced it.
Secure: Describe an experiment to demonstrate Lenz’s law.
Exceeding: Predict the location of north and south poles of a solenoid’s magnetic field when a bar magnet approaches and recedes from the solenoid.
