Temporary magnetism
Web9 Apr 2024 · A solenoid, which is a cylindrical coil that acts like a bar magnet when a current flows through it, is used in the creation of an electromagnet. By passing an electric current through the solenoid, the electromagnet becomes magnetic. However, keep in mind that the magnetism is temporary, and will disappear once the current stops flowing. WebElectromagnetism is one of the most common sources of power on the earth. The earth is constructed with a North and South Pole and a Inner core made up of metallic composites presumably and largely iron. The Magnetic field around the earth is driven largely by this source of electromagnetism.
