describe the attraction and repulsion between unlike and like poles for permanent magnets
diagrams of magnetic field patterns around bar magnets to show attraction and repulsion
describe the attraction and repulsion between unlike and like poles for permanent magnets
diagrams of magnetic field patterns around bar magnets to show attraction and repulsion
describe the difference between permanent and induced magnets
describe the characteristics of the magnetic field of a magnet, showing how strength and direction change from one point to another
diagrams to show how the strength of the field varies around them and ways of investigating this
explain how the behaviour of a magnetic (dipping) compass is related to evidence that the core of the Earth must be magnetic
describe how to show that a current can create a magnetic effect and describe the directions of the magnetic field around a conducting wire
recall that the strength of the field depends on the current and the distance from the conductor
explain how solenoid arrangements can enhance the magnetic effect
