Things made with electromagnets include:
(1) Crane: It is a powerful electromagnet for industrial use. It is passed through a large current and can be used to lift steel plates, containers, and scrap iron. wait.
(2) Telephone.
(3) Amperemeter, voltmeter, galvanometer.
(4) Electric bells, etc.
(5) Automation control equipment
(6) Industrial automation control and office automation.
(7) Packaging machinery, medical equipment, food machinery, textile machinery, etc.
(8) Electromagnetic relay.
(9) Maglev train.
Note: A device that generates electromagnetism when energized. A conductive winding matching its power is wound around the outside of the iron core. This coil carrying current is magnetic like a magnet. It is also called an electromagnet. We usually make it into a bar or hoof shape to make the core easier to magnetize. In addition, in order to demagnetize the electromagnet immediately when the power is turned off, we often use soft iron or silicon steel materials that degauss quickly. Such an electromagnet is magnetic when energized, and the magnetism disappears when the power is turned off. Electromagnets are widely used in our daily lives. Due to their invention, the power of generators has been greatly improved.
