Difference Between Electromagnet and Permanent Magnet
The key difference between Electromagnet and a Permanent Magnet is as follows:
Electromagnet VS Permenant Magnet | ||
|---|---|---|
Aspect | Electromagnet | Permanent Magnet |
Magnetism | Formed by passing an electric current through a coil of wire. | Inherently magnetic, without the need for an external force |
Adjustability | Magnetic strength can be controlled by regulating the current. | Fixed magnetic strength based on material composition. |
Temporary/Permanent | Magnetism is temporary and stops when the current is switched off. | Magnetism is permanent unless subjected to demagnetization. |
Materials Used | Requires a coil of wire and a core material. | Made of materials with natural magnetic properties. |
Applications | Used in devices requiring adjustable magnetic fields, such as motors, generators, and solenoids. | Commonly found in everyday items like refrigerator magnets, compass needles, and magnetic toys. |
Power Dependency | It depends on electric power to generate a magnetic field. | It does not require any external power to maintain magnetism. |

Electromagnet
Electromagnets are temporary magnets that form a magnetic field when an electric current is passed through them. These magnets are made by coiling a wire around an iron core. When electric current is passed through it, the iron core behaves like a magnet but when the current is turned off, it loses all its magnetic properties. Electromagnets are widely used in various devices like motors, electric bells, solenoids, etc.
In this article, we will understand the meaning of electromagnet, properties of electromagnet, advantages and disadvantages, the right-hand rule of electromagnetic field, uses of electromagnet, and the difference between permanent magnets and electromagnet.
