What is electromagnet and permanent magnet? Write the difference between them. |
| Answer» Difference between Permanent Magnet and Electromagnet is magnetic field and strength. In Electromagnet, the magnetic field is created by a wire-wound coil but the magnetic field of Permanent (Bar) Magnet cannot be changed. The strength of Permanent Magnet depends on the material used for its creation, on the other hand, the strength of Electromagnet varies according to the flow of\xa0electric current\xa0into it. Three types of Permanent (Bar) Magnets\xa0are Ceramic Magnet, Flexible magnets, Neodymium iron boron magnet, and Samarium cobalt magnet. Each has its own applications and types. Let’s see the more differences between the Permanent Magnet and Electromagnet. | |
