The difference between holding magnets and liftmagnets is that holding magnets do not have a safety factor. Note that holding magnets releases at given strength (in ideal conditions). Always use some margin.
Stated force applies in ideal conditions without safety factor.
Force: 1kg ≈ 9.8Newton
Steel plate thickness: a = 1.5mm / b = 4mm
INSTRUCTIONS FOR USE
The holding force (necessary to release the electromagnet in a perpendicular direction from the iron surface) depends on the following factors:
The gap between the electromagnet and the iron surface. The holding power is most optimal if both the surface of the magnet and the iron have direct contact, with as good surface evenness as possible.
The thickness of the iron surface. The electromagnetic force is most optimal if the thickness of the iron load exceeds 15mm.
Material. The material must be ferromagnetic. Good ferromagnetic material, from better to worse in descending order: Fe 35, steel 60, moldable cast iron, gray iron and high speed steel.
Voltage. The voltage should not be less than 90% of 24DC.
