How is the surface field measured?
The surface field of a magnet is a measure of the strength of the magnet's magnetic field at the surface of the magnet. There are several ways to measure the surface field of a magnet, including:
-
Hall Effect Sensors: These sensors use the Hall effect, which is a phenomenon that occurs when a magnetic field is applied to a conductor, to measure the strength of the magnetic field at a particular point.
-
Gaussmeters: These devices use a coil of wire and an amplifier to measure the strength of a magnetic field.
-
Magnetometers: These sensors use the magnetization of a material to measure the strength of a magnetic field.
-
Fluxmeters: These devices measure the flux, or flow, of a magnetic field through a surface.
It is important to note that the surface field of a magnet can vary depending on the location on the surface of the magnet, as the magnetic field is not uniform over the entire surface. To get an accurate measurement of the surface field of a magnet, it is necessary to take multiple readings at different points on the surface and average the results.

Great small mags make work look nice
Used these to break the connection on Security Door Sensors, the 3m tape works perfectly also.
3/4 x 1/4 x 1/4 Inch Strong Neodymium Rare Earth Ring Magnets N52 (6 Pack)
I use 4 knives on a regular basis, and my favorite knife is steel, and subject to rust. This goes on the cabinet next to the sink; keeps the knives readily visible, clean, dry, sharp, and easily selected; prevents dampness as is possible in enclosed knife holders, and saves counter space. The right size for a 12” deep cabinet, and works like a charm.
We use total element magnets in all of our products
Simple, strong, uniform magnets at the specified dimensions, shipped promptly and without fuss. These are an excellent value for the money. Haven't seen any failure so far and I've used a lot of these.
We’ll done
Very nice and quick shipping
Decided to try this Supplier instead of the one I have used for many years. Prices are much cheaper...so was hesitant at first. Magnet is just as high quality as ones more than twice the price with the same "N" ratings. With many years experience utilizing Neodymium Magnets; I feel comfortable recommending this company. Adhesive discs are also outstanding performers. Cuts down on mounting time and they have not failed yet.
I used the product on wrench racks in my toolbox. Wrenches no longer move or slide around when moving my toolbox around a giant aircraft hangar. Outstanding strength in these magnets. Worked perfectly! Need some more actually!
Received the magnets. Very strong snd met my needs perfectly.
Needle minders
However, I can’t begin to tell you how impressed I am with totalElements in every step of the order so the five star rating is for them.
They are perfect
Thank you so much👍🏻😃
Multiple uses around my metal studio. Excellent magnets.
