Electromagnet 12 and 24 V - holding force at the touch of a button!

What types of electromagnets are there?

1. Stroke magnets: These electromagnets generate a linear movement and are often used in mechanical controls or as actuators. They are ideal for moving objects in a straight line, such as in door openers or valves.
2. Holding magnets: They are used to attract and hold objects as long as current is flowing. Holding magnets are often used in safety systems or in conveyor technology to hold objects in position.

1. Industrial automation: They control machine movements, lift metallic objects or activate conveyor belts.
2. Electric motors and generators: Electromagnets are crucial for converting electrical energy into mechanical energy and vice versa, which makes them indispensable in electric motors, generators and transformers.
3. Medical technology: In medical technology, e.g. MRI machines, the strong magnetic field of electromagnets is used to create detailed images of the human body.
4. Electrical switching technology (relays and contactors): Electromagnets open and close electrical contacts to control circuits in devices and machines.
5. Door locks and security systems: Electromagnets keep doors or gates in safety applications closed until they are unlocked by power supply.
6. Magnetic cranes and lifting magnets: In the metal processing and scrap metal industry, the magnets lift heavy metal parts or scrap and enable easy transport.
7. Vehicles and transport technology: Electromagnets are used in electric motors in vehicles, in trains (maglev trains) or in braking and locking systems, such as eddy current brakes. 
8. Consumer electronics: Electromagnets can also be found in loudspeakers, microphones and other devices that convert sound or vibrations into electrical signals.

This variety of applications of magnets, shows the great importance of electromagnets in modern technologies and daily processes.

How an electromagnet works 

An electromagnet generates a strong magnetic field as soon as current flows. It consists of a coil made of copper wire that is wound around an iron core. As soon as voltage is applied, the electrons align and the magnet is magnetised. If the current is switched off, the magnetic field disappears immediately and the magnet loses its adhesive force. This property makes electromagnets ideal for applications where the magnetic field needs to be controlled in a targeted manner. Electrically switchable permanent magnets have exactly the opposite effect. This neutralises the magnetic field when current is added or the polarity is reversed and ferromagnetic objects are released. The core contains a permanent magnet with a coil which, however, generates a magnetic field of opposite polarity when current is added and thus neutralises the magnetic field of the permanent magnet. The holding force varies depending on the main components used.

The classic electromagnet consists of three main components.
The coil, which is made of copper wire wound around an iron core.
This iron core serves to amplify the magnetic field.
The more windings of copper wire around the iron core, the stronger the magnetic field of the coil can become.
Current is the third main component that sets the electrons in motion and thus generates the magnetic field.

The magnetic strength depends on the current strength, the number of turns of the wire and the material of the iron core. The more turns and the stronger the current, the stronger the magnetic field of the coil. The highest holding force is inside the coil, outside the coil the magnetic flux density is lower and decreases rapidly with distance. For this reason, this type of magnet is only effective at very short distances. An effect with a greater range or even through an object can be achieved with neodymium magnets and super magnets.

Why use an electromagnet?

On/off switchable - Magnetic force only active when current flows
Strong & flexible - Strength can be adjusted by voltage & windings
Durable & low-maintenance - No moving parts, long service life
