PPT-Magnetism

Natural Attraction without pheromones History of Magnets More than 2000 years ago rocks called lodestones were found in the region of Magnesia in Greece In the 12 th century the Chinese used them for navigating ships. Magnetism is the property of attracting iron by a magnet.. A magnet is an object made of certain materials like iron which can create a magnetic field around it. If there are things made of iron in this field (region) they are attracted by the magnet.. A unit of measure of . magnetic field strength. , the _____________, is named after him.. connected. oersted. Electricity and Magnetism. How can an electric charge create a magnetic field?. .

Demonstrate the properties of magnets.. Demonstrate and discuss the magnetic effect of electric current.. Discuss the uses of electromagnets.. 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!). 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..

Essential question:. 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
