What are the sizes of button horseshoe magnets?

 
         
  diameter of two red button horseshoe magnets 12.5mm and 32mm  

The diameter refers to the distance between the two widest points of the button horseshoe magnet’s circular surface. The diameter ranges from 12.5mm (0.5″) to 32mm (1.3″).

 
         
  Thin pieces of steel  

A large diameter button horseshoe magnet is useful for clamping two large pieces of steel together, whereas a smaller diameter would be more suited to holding thin pieces of steel. This is because the larger the diameter, the greater surface area of magnet is available to hold the large pieces of steel together.

 
         
  Height of a button horseshoe magnet 9.5mm and 25.4mm  

The height refers to how tall the magnet is and ranges from 9.5mm (0.4″) to 25.4mm (1″). 

 
         
  Indicator base held with a red button horseshoe magnet  

A tall button magnet will be beneficial whilst being used as a magnetic base. This is because it will provide added height and allow the implement, e.g. an inspection mirror, to be within an easier reaching distance of the user (it will be higher off the surface). 

 
         
  diameter of button horseshoe magnet mounting hole 4.5mm and 10mm  

The diameter of the clearance hole ranges from 4.5mm (0.2″) to 10mm (0.4″). 

 
         
  Inspection mirrors  

The diameter of clearance hole matters when purchasing a button horseshoe magnet to act as a magnetic base. This is because the diameter of the stand on the inspection mirror, for example, will dictate the diameter of the clearance hole so that they can fit together, e.g. a 9mm diameter inspection mirror stand will fit into a 10mm clearance hole. 

 
         
  Magnetic pull of a button horseshoe magnet 0.7kg and 4.8kg  

The magnetic pull ranges from 0.7kg (1.5lb) to 4.8kg (10.6lb).

 
         
  Wonkee Donkee says "The magnetic pull is the maximum weight of ferromagnetic material the horseshoe magnet can hold"
