PPT-Magnetism and magnetic fields

The Shape of Magnetic Fields Where is the magnet stronger Which direction do the arrows go What does this tell you about the Earths poles Induced and Permanent Magnets Induced Magnets A magnet that is produced when a when a magnetic material is. In addition magnetic fields create a force only on moving charges The direction the magnetic field produced by a moving charge is perpendicular to the direction of motion The direction of the force due to a magnetic field is perpendicular to the dir Dayal Wickramasinghe and Lilia . Ferrario. Australian National University. Canberra. . . The chemically peculiar . Ap. , Bp stars ( ~ 1.8 -5 . M. sun. ) are magnetic, and . have ordered large. scale fields, . Often cheap relative to other geophysical techniques.. Can be measured with ground-based or airborne equipment.. Not usually very useful when looking at sedimentary structures. (We’ll see why later!). What causes a compass to behave as it does?. Earth’s gravity. Earth’s shape. Earth’s geographic north pole. Earth’s magnetic field. Magnetic poles that are alike. attract each other. repel each other. 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.. magnetism. Faraday’s Law of Electromagnetic Induction. induced currents. electric generator. eddy currents. Electromagnetic Waves (Maxwell & Hertz). 1. Basic facts of Magnetism. Oersted. . discovered that a compass needle responded to the a current in a loop of wire. c. Investigate applications of magnetism and/or its relationship to the movement of electrical change as it relates to. Electromagnets. Simple . motors. Permanent . magnets. A. Magnetic . Forces. 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? . 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.. Crane Video. What do you know about magnetism?. Electricity and magnetism are related!. Modeling .  independent work  compare notes. Magnetism Readings. Turn and talk. …Partner closer to the door. ?. Why does a magnet exert a force on distant magnetic materials?. Why are some materials magnetic but others are not?. How do magnetic domains model magnetic behavior?. Magnetism.
