Investigate and draw the shape of the magnetic field pattern around a permanent magnet. Investigate the effect that two magnets have on each other in different orientations. 6.7.1.1 The differences between permanent and induced magnets. A permanent magnet produces its own magnetic An induced magnet is a material that becomes a magnet when it is placed in a magnetic field. Induced magnetism always causes a force of attraction. When removed from the magnetic field, an induced magnet loses most/all of its magnetism quickly. 0.5 Describe how an induced magnet is produced. Explain what is meant by a permanent magnet and give examples of materials that can become magnetised. What are the advantages of using an electromagnet rather than a permanent magnet? How can we make an electromagnet? Investigate how to make an induced magnet by stroking an iron nail with a permanent magnet. Investigate electromagnets and why they are referred to as temporary magnets. Find out why soft iron is used as the core in an electromagnet rather than steel. Investigate what affects the strength of a temporary magnet.
