This Concept Map, created with IHMC CmapTools, has information related to: Physics Secondary 2 (Electricity) Phase 2, The Electromagnet Can also be used in Electric Bell or buzzer, The Electromagnet Can also be used in Microphones, Electricity Covers many topics like: The Effects of Electricity, The Magnetic Effects of Electricity Consists of: Magnetic Effect of an Electric Current-Electromagnetism, Magnetic Effect of an Electric Current-Electromagnetism Comprises of: The magnetic circular force that attracts objects from the North to the South, Heating Effect of an Electric Current Have three important notes to remember When charges move through a wire, energy is lost to atoms in wire., The Effects of Electricity Which will branch out to many lesson objectives like: Electromagnetism, The Electromagnet Can also be used in The Maglev Train, Heating Effect of an Electric Current Can be demonstrated in the form of a kettle experiment As a kettle uses both copper and nichrome wires. In a light bulb, the heated filament/resistance wire becomes so hot that heat is also emitted, The Magnetic Effects of Electricity Magnetic Effect of an Electric Current, The Effects of Electricity Which will branch out to many lesson objectives like: The Magnetic Effects of Electricity, The Effects of Electricity Which will branch out to many lesson objectives like: The Chemical Effects of Electricity, When charges move through a wire, energy is lost to atoms in wire. E.g., a concept demonstration: Electrical Energy, The Effects of Electricity Which will branch out to many lesson objectives like: The Heating Effects of Electricity, Difference between an electromagnet and a magnet Magnet, The Magnetic Effects of Electricity Consists of: Magnetic Effect of an Electric Current, Magnetic Effect of an Electric Current Contains information like: A striaght wire is placed near a compass. When an electric current flows through the wire, the compass needle is deflected. This shows that an electric current produced magnetic effects., The Electromagnet Have types Like Large and giant ones, Difference between an electromagnet and a magnet Electromagnet, The Electromagnet Is used in Dumping sites where it can extract iron and steel metal wastes from other unwanted wastes to be recycled.
