Motor effect lesson with questions and answers

Motor effect GCSE Physics lesson including Flemming’s left hand rule, magnetic flux density, Fleming’s left-hand rule, electromagnets, motor effect practical and DC motors with questions and answers throughout the lesson. The lesson objectives are as follows: Describe how a magnet and a current-carrying conductor exert a force on one another, Show that Fleming’s left-hand rule represents the relative orientations of the force, the current and the magnetic field and Apply the equation that links the force on a conductor to the magnetic flux density, the current and the length of conductor to calculate the forces involved. The slides are fully animated and include answers to every mini plenary question and exam question. The breakdown of the slides is as follows:

Slide 1 - Title and 5-minute starter. The starter is a grid of four questions entitled ‘last week, last lesson, today’s learning and future learning’. Use this generic slide for all of your lessons by simply changing the questions and the answers each time.
Slide 2 - Lesson objectives (see above)
Slide 3 – Hinge question: What will happen when a wire with current flowing through it and the magnet are brought close to one another?
Slide 4 – A demonstration of the motor effect using a cell, a piece of wire, a screw and a neodymium magnet. This can be done as a class practical if there is enough equipment.
Slide 5 – Explanation of what the class observed in the demo/practical
Slide 6 – Definition of motor effect presented to class: A wire carrying a current creates a magnetic field. This can interact with another magnetic field, causing a force that makes the wire move.
Slide 7 - Mini plenary. Three questions of increasing difficulty. Answers animate onto the screen
Slide 8 – Introduction to Fleming’s left-hand rule (LHR)
Slide 9 – Fleming’s left-hand rule visual aid with useful acronym
Slide 10 – Worked example of how to use Fleming’s LHR
Slide 11 – Mini plenary. Students attempt to use Fleming’s LHR to work out the direction of movement. Answers animate onto the screen
Slide 12 – Introduction to the calculation of forces involved in the motor effect
Slide 13 - 𝐹=𝐵𝐼𝑙 equation, with symbols and units given
Slide 14 – Worked example using the 𝐹=𝐵𝐼𝑙 equation
Slide 15 – Mini plenary. Questions testing students’ knowledge of the 𝐹=𝐵𝐼𝑙 equation. Answers animate onto the screen
Slide 16 – ALT (Applied Learning Time) Students work independently during this stage of the lesson, answering questions linked to the objectives of the lesson. Answers animate onto the screen at the click of a button.
