Physical Sciences: Mysterious Magnets

Explore how a non-contact force, magnetism, interacts with everyday objects. Students will investigate the behaviour of a variety of materials when placed near a magnet and classify objects as magnetic or non-magnetic. Students will use their experiences to identify the attraction and repulsion of objects due to magnetic forces, identify the presence of magnetic field lines and develop an understanding of the non-contact nature of magnetism.

Properties of magnetic field lines

The space around a magnet where its magnetic force is felt is called its magnetic field. Magnetic field lines form a closed loop, emerging from the north pole and merging at the south pole. Inside the magnet, the magnetic field lines move from its south pole to its north pole. The relative strength of the magnetic field lines is shown by the degree of closeness of the field lines. No two magnetic field lines can intersect each other.

Electromagnetism: Domain Theory

Explores magnetic forces from early experiments to the concepts of electromagnetic induction, the motor principle, generators, and transformers. Also looks at modern theories about the Earth's magnetic field in the extinction of species, and the ways animals use it for navigation.

Part 2: Electromagnetic Induction

This programme provides a more detailed investigation of how moving a magnet near a conductor produces electricity - electromagnetic induction.

It looks specifically at magnets inducing electron flows; solenoids, generators and alternators; transformers; Lenz's law, induction coils, back EMF and eddy currents; generators; and motors.
