Reading: Chapter 16, pp. 331-39; Chapter 20, pp. 411-18, 425-29, 431-33 . Discuss the nature of magnets, particularly with reference to poles.. Demonstrate the properties of magnets.. Demonstrate and discuss the magnetic effect of electric current.. Discuss the uses of electromagnets.. Magnets and magnetic fields. Magnets and magnetic fields. Magnets got their name from the region of Magnesia, which is now part of modern-day Greece.. The first naturally occurring magnetic rock, called . SrIr. 1−x. Sn. x. O. 3. indicated this material was a Slater insulator. This is a rare insulator where the magnetism controls the conduction of electrons. The behavior can be controlled by altering the Sn content.. Part 5 Electricity and Magnetism. © . G. . Dzyubenko. 2016. Chapter 24 Magnetism. Ch24: Magnetism. 2. This lecture will help you understand:. Magnetic . Force. Magnetic Poles. Magnetic . Field. Investigate and describe that magnets can attract magnetic materials and attract and repel other magnets.. What is Magnetism?. Let’s . Explore. What happens if you put together two magnets?. Do they become stronger together? . With a partner, take the list of everyday objects provided by the teacher and identify those objects that have or use magnets.. http://www.first4magnets.com/magnets-in-the-house-i75. Essential question:. Magnetism from electricity. In 1820, Danish scientist . Hans . Christian . Oersted. discovered accidently that when electricity passed through a wire…a magnetic field was created. Which way would the compass needles point if we placed them around the wire?. material due to the arrangement of its atoms, particularly its electrons.. Lik. e poles will repel, opposite poles will attract.. Magnetic field lines describe the structure of magnetic fields in three dimensions.. nrnmagnetism can be traced back to the Greek philosopher Thales in the 6th Century BC However it was not until 1600 that the modern understanding of magnetism began 1600 Dr William Gilbert published
