Thinking about actions to take: Electromagnets at Work
Teaching Guidance for 11-14
There's a good chance you could improve your teaching if you were to:
- relate the actions of electromagnets to those of permanent magnets
- be very clear to separate electrical loops from magnetic fields
- construct careful step-by-step accounts of the action of devices
Work through the Physics Narrative to find these lines of thinking worked out and then look in the Teaching Approaches for some examples of activities.
- conflating the field with the coil producing the field
These difficulties are distilled from: the research findings; the practice of well-connected teachers with expertise; issues intrinsic to representing the physics well.
