Maximum holding capacity of a magnet
The holding capacity indicated in the data shown is always indicative only. It is measured using a smooth sheet of metal with the optimal thickness. The tensile force acts perpendicularly. With a force acting parallel to the sheet, i.e., when the magnet moves along the sheet, the magnet's lifting capacity is significantly lower.
Maximum lifting capacity is achieved by using a sufficiently thick sheet metal containing a high iron content. Using high-carbon steel sheet metal or cast iron will result in lower lifting capacity. Lifting capacity is also affected by the magnet’s operating temperature. A heated magnet will have lower lifting capacity.
Maximum holding capacity is measured using a smooth sheet of metal with a thickness appropriate to the size and grade of the magnet being tested. The tensile force is always measured perpendicularly.
ATTENTION: If the magnet is to be used parallel to the sheet, the lifting capacity will be significantly lower!

It is also affected by the magnet’s operating temperature. A heated magnet will have lower lifting capacity.
OTHER FACTORS TO TAKE INTO CONSIDERATION ARE:
- Distance between the magnet and the sheet metal, due to painting or galvanic coating of the sheet metal,
- Any roughness, irregularity, or dirt on the sheet metal
- Operating temperature
- Humidity of the working environment
- Chemical composition of the sheet metal (magnetic conductivity)
- Sheet metal thickness
- Intrinsic stability (positioning of the magnet relative to the sheet metal size)
