China Neodymium And Ferrite Magnets Manufacturer & Supplier 
1/2 inch neodymium magnets (typically 12.7mm neodymium magnets) are a popular size among customers due to their moderate dimensions. They are widely used in various industrial, electronic, and everyday applications. The following sections will provide an overview of their properties, including pull force, surface magnetic field strength, shape types, and coating options.
1/2 inch neodymium magnet pull force
The pull force range of a 1/2 inch neodymium magnet is quite broad and depends on factors such as shape, grade, contact area, and pull force direction. Typically, the pull force range is around 2 to 15 pounds.
For example: 1/2 inch x 1/2 inch neodymium cylindrical magnet, N42 grade with a surface magnetic flux density of approximately 4,850 Gauss and a pull force of approximately 14.5 pounds. 1/2 inch x 1/16 inch neodymium disc magnet, N48 grade with a pull force of approximately 3.5 pounds. 1/2 inch x 1/4 inch neodymium iron boron circular magnet, N52 grade with a pulling force of approximately 13 pounds and a surface magnetic field strength of approximately 5000 Gauss. 1/2“ x 1/4” x 1/4" neodymium block magnet, N45 grade, with a pulling force of approximately 9.6 pounds.

1/2 inch neodymium magnet Gauss (magnetic field strength)
Gauss is the unit used to measure the magnetic field strength of a magnet. For a 1/2-inch diameter neodymium magnet, the surface magnetic field strength typically ranges from 2000 to 4800 Gauss. The grade and thickness of the magnet have a significant impact on the Gauss value.
Common shapes of 1/2 inch neodymium magnets
The most common shape for 1/2-inch neodymium magnets is circular, with common sizes including 1/2“ x 1/8”, 1/2“ x 1/4”, 1/2“ x 3/8”, 1/2“ x 1/2”, 1/2“ x 3/4”, etc. Other commonly used shapes include cylindrical, ring-shaped, square, rectangular, etc.
1/2 inch neodymium magnet coating options
To protect neodymium magnets from oxidation and corrosion, they are typically coated on their surfaces. Zinc plating and nickel plating are the most common options, with nickel plating offering better protective capabilities. For more harsh environments, epoxy and Parylene coatings can also be selected.
