Electro Holding Magnet – Things You Need to Know

Electro Holding Magnet – Things You Need to Know What Is A Holding Electromagnet? Holding electromagnets are used to attract and hold ferromagnetic pieces. The maximum force efficiency is achieved with the piece to be hold above the attraction’s face and in direct contact with both poles (outside pole and inside pole). How Does A [...]

Electromagnetic Transmissions Solenoids Holding Magnets

Electromagnetic Transmissions Solenoids Holding Magnets Solenoids for simple operation Single-acting solenoids are for common applications. The magnetic field delivered by the coil upon power-up attracts the core. Then, the nucleus becomes free again in the absence of current. They are thus available in different designs, folded sheet, square profiled, machined in the mass. Solenoids for [...]

Solenoids

Electromagnet or solenoid are general terms for all types of electromagnetic actuators. Basically, electromagnets or solenoids are devices that generate a magnetic field by means of an energized coil, guiding it through suitable iron parts with air gap. Here, magnetic poles are created inbetween which a magnetic force of attraction, the magnetic force, prevails. If [...]

Electromagnetic Radiation Definition

Electromagnetic Radiation Definition Electromagnetic radiation is self-sustaining energy with electric and magnetic field components. Electromagnetic radiation is commonly referred to as "light", EM, EMR, or electromagnetic waves. The waves propagate through a vacuum at the speed of light. The oscillations of the electric and magnetic field components are perpendicular to each other and to the [...]
