What Are the Popular Sizes of Neodymium Bar Magnets?

NdFeB bar magnets, 1 inch long and 1/8 inch wide


This is a popular rectangular NdFeB magnet in the US market, with dimensions of 1 inch long, 1/8 inch wide, and 1/16 inch thick. The N52 grade and thickness direction give the bar magnet a pulling force of about 1.2 kg. NdFeB bar magnet 1"x1/8"x1/16" is widely used in personal applications and industrial production. Custom coatings, special packaging, and cheap prices are available for block bar magnets.


Features of NdFeB magnets:


  • Remanence (Br): NdFeB N52 bar magnet at 14300-14800 gauss.

  • Coercivity (Hcj): ≥876.

  • Maximum energy product (BH-max): N52 NdFeB bar magnet is 50-53 MGOe.

  • Maximum working temperature: 60℃.

  • Corrosion resistance: NdFeB bar magnets need to be plated.


NdFeB bar magnets 3/2


3/2"x 1/2"x 1/16" is one of the most popular sizes among neodymium bar magnets for sale, also available as a standard magnet in the US. Magnets can be customized with N35 to N52 grades. Nickel plating gives the sturdy bar magnets 3/2"x 1/2"x 1/16" a shiny appearance, resembling stainless steel. When magnetized through the thickness, they can have 3M adhesive backing. N52 rare earth NdFeB bar magnet has a pulling force of 3.6 kg. Retail packaging is available for dealers.


Features of NdFeB magnets 3/2:


  • Remanence (Br): 14300-14800 gauss for N52 rectangular NdFeB block magnet at 3/2"x1/2"x1/16".

  • Coercivity(Hcj):≥ 876.

  • Maximum energy product (BH-max): N52 rectangular NdFeB block magnet is 50-53 MGOe.

  • Maximum working temperature: 60℃.

  • Corrosion resistance: 3/2"x 1/2"x 1/16" NdFeB bar magnets need to be plated.


NdFeB bar magnets 60x10x3mm


60x10x3mm is a popular size in the rare earth NdFeB block magnet category. The highest grade of N52 provides the magnet with a force of about 16.27 pounds.


Nickel plating provides a shiny appearance to the rectangular NdFeB magnet 60x10x3mm. Strong rare earth NdFeB magnets are used for scientific purposes, arts and crafts, or school classrooms and DIY projects.


If the price is low, choose low-grade NdFeB magnets with a size of 60x10x3mm, such as N40, N38, and N35.


Features of NdFeB magnet 60x10x3mm:


  • Remanence (Br): NdFeB bar magnets N52 is 14300-14800 gauss.

  • Coercivity (Hcj): ≥876 kA/m

  • Maximum energy product (BH-max): N52 NdFeB block magnet is 50-53 MGOe.

  • Working temperature: ≤60℃.

  • Corrosion resistance: NdFeB magnets must be plated to prevent corrosion.


NdFeB bar magnets 60x10x5mm


This is a common size in the rare earth NdFeB block magnet category with a size of 60x10x5mm. Magnetization can be customized through thickness, with the magnetic pole on the largest surface, while others can be magnetized. The 60×10×5 mm rare earth NdFeB magnet here is made of N52 grade, which can generate about 14kg of magnetic force.


Features of 60x10x5mm NdFeB magnet:


  • Remanence (Br): 14300-14800 gauss for N52 rectangular NdFeB block magnet.

  • Coercivity (Hcj): ≥876 kA/m.

  • Maximum energy product (BH-max): N52 block NdFeB magnet is 50-53 MGOe.

  • Maximum working temperature: ≤60℃.

  • Corrosion resistance: NdFeB magnets need to be plated to prevent rusting.


NdFeB bar magnets 3 inches x 1/4 inches x 1/4 inches


3 inches x 1/4 inches x 1/4 inches (76.2 x 6.35 x 6.35 mm) is the standard size of rectangular NdFeB magnets in the US market. The N52 grade provides the NdFeB magnet 3 inches x 1/4 inches x 1/4 inches (76.2 x 6.35 x 6.35 mm) with amazing pulling force and countless uses. Nickel-copper-nickel plating prevents NdFeB magnets from rusting. Specified packaging can be done on strong bar magnets.


Features of NdFeB magnets:


  • Remanence (Br): NdFeB N52 block bar magnet is 14300-14800 gauss.

  • Coercivity (Hcj): ≥876.

  • Maximum energy product (BH-max): N52 block NdFeB magnet is 50-53 MGOe.

  • Maximum working temperature: 60℃.

  • Corrosion resistance: Rectangular NdFeB magnets need coatings.
