Properties of of waves including light and sound. This means that the north and south poles of the magnetic field is continuously changing, and thus randomizing the domain orientation in the magnet causing it to lose magnetism. By bringing a permanent magnet close to a magnetic material, field line cause domains in the material to arrange themselves, resulting in magnetic field which interact with the field lines of the . Describe methods of magnetisation by use of direct current in a (d.c) coil. Hazards: Damaged insulation: contact with the wire (live wire especially) due to gap in the insulation causes electric shock which can cause serious injury or shock. Dangers of Electricity. Use the concepts on which Maxwell's equations are based to explain why moving a permanent magnet past a loop of wire causes an electric current to flow in the wire. Simple phenomenn of Magnetism.pdf - SIMPLE PHENMENON OF If you continue to use this site we will assume that you are happy with it. Because this process happens very quickly, no appreciable thermal conduction occurs and the expansion is essentially adiabatic. Magnets have two poles: a north and a south. It will have a North and South pole and creates a field whereby field lines run from north to south pole. Page 158 Section 4.2 Electrical quantities. These materials are calledferromagnetic materialsand they have the ability to becomemagnetized. Heating a magnet to a high temperature also demagnetize it. An alternating current on the other hand is a type of current that constantly changes direction. You can actually deduce the polarity of the electromagnet by looking at the direction of thecurrentat the ends of the solenoid.

Ferromagnetic materials can be magnetized by placing them inside the coil like so: NOTE:Conventional current is the flow ofpositive charge. Simple phenomena of magnetism - Flashcards in IGCSE Science Once the electricity is turned off, the magnetism will also switch off along with it. Since the direction of current determines the polarity of the magnet, it is important to understand that the current must flow in a single direction (direct current) in order to magnetize the metal. The metal inside the coil is called a solenoid. Heat the magnet.
