Working Principle of Electromagnet
The working principle of electromagnets depends on the relationship between electric currents and magnetic fields. When an electric current flows through a conductor, for example, a wire, it produces a magnetic field around it. By coiling the wire, the resulting magnetic field is strengthened. This coil, when connected to a power source, becomes an electromagnet.
- The strength of the magnetic field can be controlled by adjusting the electric current.
- This property makes electromagnets versatile and widely used in various applications, from everyday devices like doorbells to more complex systems such as magnetic resonance imaging (MRI) machines in healthcare.
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.
