The height refers to the distance between the bottom of the magnetic poles and the top of the arch. It can range from 11.1mm (0.43″) to 54mm (2.1″).
The width refers to the distance between the two widest points and can range from 7.9mm (0.31″) to 79mm (3.1″).
A wide power horseshoe magnet is particularly useful for sorting through corrosive materials for anything ferromagnetic. This is because a wider surface area of corrosive materials can be sorted through for any ferromagnetic materials.
The depth ranges from 7.9mm (0.31″) to 85.7mm (3.4″).
A thin power horseshoe magnet would be beneficial in a small diameter plating vat that does not require a large magnet to retrieve the ferromagnetic material. A thick power horseshoe magnet, however, could be used to collect large quantities of ferromagnetic material from a large plating vat.
The diameter of the clearance hole ranges from 7mm (0.28″) to 9.5mm (0.37″).
The size of the clearance hole on the power horseshoe magnet you choose should be down to the diameter of the pole or chain you wish to attach. For example a 9mm diameter chain can be inserted into the clearance holes to suspend the power horseshoe magnet over a vat of corrosive liquid.
The magnetic pull ranges from 0.9kg (2lb) to 60kg (132lb).
The best size of power horseshoe magnet to use would be 79 x 54 x 85.7mm (3.1 x 2.1 x 3.4″) which has a magnetic pull of 60kg (132lb), the largest size available. This is because the main difference between a power horseshoe magnet and any other horseshoe magnet is its strength. Therefore the size of its magnetic pull should be taken into consideration.
