WebPhysics Notes for Class 12 Chapter 5 Magnetrism And Matter The property of any object by virtue of which it can attract a piece of iron or steel is called magnetism. Natural Magnet A natural magnet is an ore of iron (Fe 3 O 4 ), which attracts small pieces of iron, cobalt and nickel towards it. Magnetite or lode stone is a natural magnet. WebEarth’s magnetic field is also referred to as the geomagnetic field. The earth’s magnetic field extends millions of kilometers into outer space and looks very much like a bar magnet. The earth’s south magnetic pole is actually near the North Pole and the magnetic north pole is in Antarctica! WebElectromagnetic Induction. Electromagnetic induction class 12 notes Induced Emf.
