The 5V Electromagnet - 10 Kg Holding Force - P30/22 is a compact and powerful magnetic solution for makers, hobbyists, and engineers. When supplied with 5V DC (4–6V range), it generates a strong holding force of up to 10 Kg, making it perfect for gripping, locking, or lifting ferromagnetic materials. With simple on/off control, this electromagnet allows precise handling in automation, robotics, security locks, and DIY experiments. Actual lifting capacity depends on surface contact and material type, with an effective pickup weight of around 2 Kg. Designed for durability and consistent performance, this electromagnet is a reliable choice for your creative and industrial applications. Featured By RoboticsBD.

Working Principle:
An electromagnet is simply a coil of wire. It is usually wound around an iron core. However, it could be wound around an air core, in which case it is called a solenoid. When connected to a DC voltage or current source, the electromagnet becomes energized, creating a magnetic field just like a permanent magnet. The magnetic flux density is proportional to the magnitude of the current flowing in the wire of the electromagnet.
The polarity of the electromagnet is determined by the direction of the current. The north pole of the electromagnet is determined by using your right hand. Wrap your fingers around the coil in the same direction as the current is flowing (conventional current flows from + to -). The direction your thumb is pointing in the direction of the magnetic field so north would come out of the electromagnet in the direction of your thumb. DC electromagnets are principally used to pick up or hold objects
We supply many varieties of electromagnets with a higher power as well as lower, original dimensions, etc to satisfy your unique requirements.

Precaution:
Electromagnets must meet the following conditions to achieve maximum suction:
- The object to be sucked must have good magnetic permeability.
- Proper use of power supply, rated voltage.
- The object to be sucked must be flat and clean.
- The object to be sucked must be greater than or equal to the surface of the magnet( For example the magnet is 20 x 15 mm, so the surface area is S=r²π=10²π mm² so the object to be sucked must be greater than or equal to 10²π mm² )
- The object to be sucked must be greater than 5mm. (If the thickness decreases, the suction decreases)
- The object to be sucked must be close, the middle can’t be interspersed with objects or gaps
- Suction means more than 5cm in thickness, surface roughness, the surface is greater than the cross-sectional area of the electromagnet and maximum suction completely fit together on an iron-based material.
- Electromagnet in working condition electromagnetic conversion would produce a certain amount of heat, electricity more frequently the higher temperature, which is a normal phenomenon.
