Magnetic Product Description:

This rare earth block magnet has a length of 20mm, a width of 10mm and a thickness of 5mm. It has a pull strength of 7.41kgs and is identified by AMF part number 22023A.

Uses for our rare earth block magnets:

Small Neodymium Block magnets are great for a wide variety of applications due to their impressive strength to size ratio. This block magnet, in particular, is only 20mm x 10mm x 5mm but it has the incredible pull force of 7.41kg! It is stronger than other rare earth magnets of its size due to the high grade of N52, meaning you don’t have to sacrifice size for strength as this magnet is still very compact. Due to their significant strength, these Neo blocks can be used for multiple applications requiring a strong hold but a seamless finish. The magnet can be easily hidden from sight, behind or within an item. They are often used for sensor applications as well as within small electric motors.

Bought 5 magnets with different strengths the same time

The delivery was on time and I am glad about it. The packaging made me crazy. When I open it all five were stuck together and only the elephant can separate them and I could not use them straight away. When the smallest two got separated one got broken and hurt my hand between the other strong magnets. I might need to buy more but am scared of these magnets arrive stuck and unable to separate and end up with a broken piece in my hand. Quality is good as promise and thank you.

AMF Magnetics reply: Hi there, thank you for your feedback – we will let our warehouse know. Have a look at the Magnetic Handling and Separating Guide which would have been included in your order, it'll show you the easiest and safest way to separate your magnets. Let us know if you haven't received one and we can email you a copy.

Great Product and Great Customer Service

Thanks for the great magnets and for the excellent customer service. I had a magnet that broke the moment I opened it from the packaging. I wrote back to suggest a slight improvement to the way they might deliver this type of magnet in the future. I wasnt looking for a replacement because I felt I would still be able to use it....but I just wanted to let them know. They suggested they'd send a replacement... I emailed back and said that really is not necessary.... they sent a new one anyway!! Thank you.

These guys really stand behind their products!

No FAQ available

NB: Ranges are indicative for product category, please check individual products for specic values within that range.

The most common coating for Neodymium magnets is Nickel + Copper + Nickel (Ni + Cu + Ni). This coating offers the magnet relatively good protection from corrosion and passive applications. If the magnet will be exposed to moisture or liquid then consider the use of an organic coating such as Epoxy. A hard wearing coating, Epoxy is suited to applications where the magnet will come under some friction or knocking.

Magnets are readily available in Blocks, Discs, Cylinders & Rings. AMF Magnetics specializes in the supply of short-run prototype magnets including Arc Segments, various magnetic orientations etc. If you need a magnet size that we don't carry in stock, submit a Design-a-Magnet enquiry for a quote on your custom magnet design.

Neodymium magnets are offered in several different grades. The first section N30-54 has an operating temperature of up to 80 degrees. Most of our stock only goes up to N38. The second section, denoted with the "M" prefix after the grade has an operating temperature 100 degrees. After this the grades are "H", "SH", "UH" & "EH". In order for the magnet to withstand a higher operating temperature, during production more of the raw material PrNd is incorporated as these elements have a naturally occurring resistance to high temperatures.
