What is the strongest magnetic clasp for jewelry?

You might told that a lobster clasp is the strongest magnetic jewelry clasp. However, does the magnetic strength rely on the type of jewelry clasps?

Actually, that’s not the case. The magnetic strength of a stainless steel clasp depends on the grade of magnet used, not the type of jewelry clasps.

As a manufacturer of stainless steel magnetic clasps with a decade of experience, I’d like to share a purchasing tip to help you find magnetic jewelry clasps with strong magnetism more effectively.

Stainless steel can become magnetic after processing, but its magnetic force isn’t particularly strong. Without adding a magnet, it’s difficult for it to meet practical needs, so a magnet is indispensable.

Magnets are used in various industries. In the stainless steel magnetic jewelry clasp industry, N series(N35-N45) magnets are commonly used. They include:

N54
N52
N50
N48
N45
N42
N40
N38
N35

Generally, higher numbers indicate stronger magnetism.

Some customers may specify the magnet size and grade like this:

ø4*3  N42

ø4*3  N45

ø4*3  N48

Here, ø2.5*3 refers to a diameter of 2.5mm and a thickness of 3mm. For the same magnet size, using an N48 magnet in a stainless steel clasp will offer stronger magnetism compared to an N42.

Smaller and thinner magnets generally require higher grade magnets.

So, when you’re searching for strong magnetic clasps for jewelry, you should pay attention to the grade and size of the magnet used in the clasp to understand its specific strength.

This detail can be customized according to the type of magnetic jewelry clasps you’re interested in.

If you’re buying for personal use, feel free to ask the seller about the grade of magnet used.

This information is rarely provided by sellers in product descriptions, but some may list the magnet size.

So when you are looking for strong magnetic clasp for jewelry, you need to consider the magnet grade and size. This is because, for the same type of magnetic jewelry clasps, the magnetic strength can vary.

Furthermore, the method of attaching the magnets to the jewelry clasp is vital in determining the strength and reliability of a magnetic clasp. When the magnets are securely and smoothly incorporated into the clasp, they produce a strong magnetic force that effectively secures your jewelry or accessories. This is because a firm and seamless attachment ensures an even distribution of the magnetic field, avoiding any weakening from gaps or inconsistencies. In contrast, if the magnet is poorly attached or inset, it can reduce the strength of the magnetic field.
