Question 3

How Do I Test The Magnetic Strength Of My Magnet?

Accepted Answer

Magnet strength can be determined by using a gauss meter or hysteresis graph. But, most important is to test the magnet in the application where possible. If your magnet is being used in a motor, then you will want to test the flux density of the entire magnetic assembly using a coil, or measuring torque. If your magnet is being used in a holding application, then testing pull or shear force will be required. Selecting the correct magnet at the beginning is very important, but making sure the magnet is performing according to your specification each time will determine the appropriate test needed.

Question 4

How Do I Handle Large Neodymium Magnets?

Accepted Answer

Always wear a pair of gloves. When you are going to separate one magnet from the other magnet(s), put the magnets on a durable non-metal surface of a stable table with the magnet to be separated hanging off the edge of the table. Use one hand to firmly hold the other magnets on the table. Use the other hand to hold the magnet you are separating firmly. Push it down and away from the other magnets until you no longer feel any magnetic attraction. Note that whenever we ship magnets with strong strength, we always include a safety guideline in handling the products in the package. Please read the instruction first. Please contact us, if you have any questions in that regards.

Question 5

Can I Drill A Hole Or Machine The Neodymium Magnets?

Accepted Answer

Yes, if unmagnetized, you can easily to machine the magnets with the right tools, like diamond drill bit or EAD machine. But if the magnets are already magnetized, you need to keep the magnet cool during the machining process. Also since the magnets are fragile, the machine process should be slowly done.

Question 6

Will A Magnets With A 10lb Pull Strength Lift A 10lb Object?

Accepted Answer

Our pull strength is tested under ideal conditions, so in real life applications you probably will not achieve the same strength. The Pull Force we measure shows how much weight it takes to pull the magnet off a piece of steel when in between 2 pieces of steel. If the application uses just a magnet to metal application then the pull force is about half of what we show. You can probably get a few more pounds but you probably won’t get the same results we achieve under perfect conditions.

Question 7

How Do You Measure The Pull Strength Of Your Magnets?

Accepted Answer

The pull strength of our magnets is measured by how much force it takes to pull the magnet off a steel plate when in between 2 steel plates.

Question 8

Question 9

What Is The Strongest Magnet That I Can Get?

Accepted Answer

Neodymium magnets are the strongest materials available, and range in strength from 35 mgo to 55 mgo. But the more important question should be “what is the correct magnet strength that I need for my application?” Call one of our technical sales people to understand what material strength may be...

Question 10

Are There Any Health Or Safety Risks With Neodymium Magnets?

Accepted Answer

There are no known health risks caused by being exposed to neodymium magnets. There can be issues if the person has a pacemaker, so you should consult your doctor for information on this. Some people actually believe magnets can have health benefits and help the healing process. There are...

Question 11

What Will Cause A Magnet To Demagnetize?

Accepted Answer

In general, if you have selected the correct magnet for your application, you should not see any demagnetization of a magnet. However, some of the factors that can cause demagnetization are exposure to very high and low temperatures, another magnetic force, or shock. If you are unsure of the...

Question 12

Is Temperature A Concern With Neodymium Magnets?

Accepted Answer

Yes. Neodymium magnets are sensitive to heat. There are two temperatures which are critical to the neodymium magnets, i.e. the operating temperature and the curie temperature. For example, the maximum normal operating temperature is 175 F (80 C) for standard N-series grades. If the magnets are...

Question 14

Can You Supply Magnet Catalogue ?

Accepted Answer

As magnets manufacturing , we can custom-made various of magnets with different grade and dimension, from N35 to N52 , M, H, SH,UH, AH, EH series , and different shape such as ring , disc , block ,arc and more. In addition to magnets dimension, other relative information can be found in our...

Question 15

Do You Have A Minimum Purchase Order?

Accepted Answer

The manufacturing of magnets is a complex process, please check our production flow for more information. As considering the production time and cost, we suggest the batch order value should be more than US$3000 per time; Of course, if less than US$3000, we also would like quote our offer for your kind consideration, so we have no strict MOQ .

Question 16

May We Get A Sample Of The Product? How To Ship And How To Pay ?

Accepted Answer

Yes,the samples testing should be necessary for first time , we would like cooperate for samples. If its regular magnets and we have stock , we would like supply free samples for customers, if need new production , we will quote samples fee and we can accept T/T, Paypal , Western Union , Alibaba trade assurance for payment.

Question 17

How Many Days Does It Take To Ship My Order?

Accepted Answer

In generally, the sintering NdFeB and SmCo magnet production time is 15-25days, cast AlNiCo will take 25-30days , the magnetic assemblies will be about 30-40 days for your reference , the exact time need to be checked before the order .
