What materials can I use to block/shield magnetic fields?
Magnetic fields cannot be blocked, only redirected. The materials that will redirect magnetic fields are materials that are ferromagnetic (attracted to magnets), such as iron, steel (which contains iron), cobalt, and nickel.
-
Iron: Iron is a ferromagnetic material, which means it is strongly attracted to magnets and can be used to block a magnetic field.
-
Steel: Steel is also ferromagnetic and can be used to block a magnetic field.
-
Mu-metal: Mu-metal is an alloy that is made up of several ferromagnetic materials, including nickel, iron, and cobalt. It is highly effective at shielding magnetic fields.
-
Other Metals: Other metals, such as brass, copper and aluminum can also be used to block or shield against magnetic fields, but they are not as effective as iron, steel, or mu-metal.
It is also possible to reduce the strength of a magnetic field by increasing the distance between the magnet and the object you want to protect. The strength of a magnetic field decreases with distance, so increasing the distance between the magnet and the object will reduce the strength of the field.

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.
