Characteristics of Electromagnets
Characteristics of electromagnets are as follows:
- Control Magnetic Field: Electromagnets can adjust their magnetic field strength by controlling the electric current, ensuring a precise magnetic field.
- Temporary Magnetism: It exhibits magnetic characteristics only when an electric current is present, enabling flexible activation and deactivation for specific applications.
- Versatility in Design: Comes in varied shapes and sizes, such as flat-faced, cylindrical, and specialized configurations, adapting to diverse industrial and technological needs.
- Industrial Use: Widely employed in industry for tasks like material handling, sorting, and efficient lifting of ferrous materials due to robust magnetic fields.
- Safety: The temporary magnetic field enhances safety, allowing easy control and manipulation of magnetic force in different settings.
- Energy Efficienct: Consumes power only during active magnetic field generation, contributing to economical energy usage.
- Technological Applications: Vital in various technologies, including electric generators, MRI machines, and electric door locks, showcasing versatility in different technological domains.
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.
