A strong magnet is a strong NdFeB Magnet. It has better performance than ferrite. A strong ndfeb magnet can absorb 640 times its own weight, hence the name "King of Magnetism".

What is the quality of the powerful magnets you buy on the market? What is the fast detection of strong Ndfeb magnet quality detection method?

The quality of ndFeb detected by strong magnet is evaluated from two aspects: 1. Product performance; 2. Product appearance

I. Product Performance:

Strong NdFeb magnet is a unified standard, the main understanding of the index is remanence, coerce, magnetic energy brand. Strong NdFeb magnets of different sizes can be resolved by Gauss. The quality and performance of this magnet can be resolved by Gauss. Coercive force can only pass magnetic characteristic tester, which is generally not available for user test.

Ii. Product Appearance:

It can be picked up to test the appearance of the product, mainly from five aspects:

(1) Pitting point: including bubbles. Scar, electroplating tumor, slag layer, local excessive thickness;

(2) Edge: edge collapse, material residue;

(3) Scratches: knife marks, line marks, fingernail scratches, etc.;

(4) Crack: cracking, etc.;

(5) Sandhole: pinholes, pores, particles, etc., but also to see if there is a missing edge off Angle, electroplating is in good condition, the size meets the design requirements, ndfeb magnets are plated to prevent corrosion and rust on the surface of the magnet. The size of the magnetic force can be distinguished by placing the same size on an adsorbable surface.

Demagnetization curve analysis can also be used to understand the measurement of magnetic properties of a magnet.

Above is the detection of strong Ndfeb magnet quality method, I hope to help you how to quickly identify the quality of strong magnets.
