How strong is a 30mm neodymium magnet?

30mm neodymium magnet usually refers to the magnet's diameter or length is 30mm rare earth neodymium iron boron magnets, applications are very wide, its surface magnetic strength and tensile strength need to know the specific size, the following content will be a variety of shapes to expand the introduction.

The picture shows 30x10x0.8mm galvanized neodymium block magnets.

NdFeB magnets come in a variety of shapes, with 30mm diameter round magnets being one of the most common shapes. These magnets typically have a large surface area and can generate a strong magnetic force for applications that require a large magnetic field. In addition to round shapes, 30mm magnets can also be manufactured in square, toroidal, and curved shapes, depending on the application.

Different shapes 30mm neodymium magnets pull strength reference;

Diameter 30mm, thickness 1mm neodymium round magnet, N35 grade pull strength about 0.2kg.

N35 grade 30x2mm round magnet, vertical pull strength about 0.8kg

N52 grade 30x30mm round magnet, vertical tensile strength about 50kg.

N35 grade 30x5x5mm ring neodymium magnet, vertical pull approx. 3kg

30x20x5mm rectangular neodymium magnet, N35 grade vertical pull approx. 5kg

30x10x10mm sintered neodymium block magnet, N35 grade vertical pull approx. 9.2kg

30x10x2mm neodymium iron oh block magnet, N42 grade vertical pull about 1.4kg.

Attention: The shape, contact area, thickness, and material grade of neodymium magnets can all affect their strength.

For a specific 30mm NdFeB magnet, its magnetic force can be estimated in the following ways:

Magnetic flux density: the magnetic field strength at the surface of the magnet can be measured directly using a Tesla meter or Gauss meter.

Pull test: The maximum tensile force between the magnet and the iron plate is experimentally determined, which is a visual measure of the magnet's strength.
