How can I do this? Which magnets work for this? Ordering Questions. I am trying to order online, but every time I add something to my shopping cart, I get a message that my cart is empty.

Can you just put my magnets in a small envelope to save postage? Where can I get a discount code? Where are you located? Do you have a local distributor near me? Do you have a printed catalog? How can I identify the poles of the magnets? There are several simple methods that can be used to identify the Scientific North and South poles of neodymium magnets.

The North pole of the marked magnet will be attracted to the South pole of the unmarked magnet. This actually contradicts the "opposites attract" rule of magnetism, but the naming convention of the poles is a carry over from the old days when the poles were called the "North-seeking" and "South-seeking" poles. These were shortened over time to the "North" and "South" poles that we know them as.

Please note: In some magnetic therapy applications, the definitions of the poles are reversed from the scientific definition described above. Please be sure to confirm the proper definition of the poles prior to using magnets for medical purposes Also check out our article, Which Pole is North? Is one pole stronger than the other? No, both poles are equally strong. Which is the strongest type of magnet?

Neodymium more precisely Neodymium-Iron-Boron magnets are the strongest permanent magnets in the world. What does "Magnetized thru thickness" mean? We use the description "Magnetized thru thickness" to identify the locations of the poles on our block magnets. The thickness is always the last dimension listed for block magnets. If you take one of our block magnets and place it on a flat surface with the thickness dimension as the vertical dimension, the poles will be on the top and bottom of the magnet as it sits.

For example: Click here for Magnetization Directions Illustrated. What materials do magnets attract? Ferromagnetic materials are strongly attracted by a magnetic force. The elements iron Fe , nickel Ni , and cobalt Co are the most commonly available elements. Steel is ferromagnetic because it is an alloy of iron and other metals. Magnetic fields cannot be blocked, only redirected. The only materials that will redirect magnetic fields are materials that are ferromagnetic attracted to magnets , such as iron, steel which contains iron , cobalt, and nickel.

The degree of redirection is proportional to the permeability of the material. The most efficient shielding material is the 80 Nickel family, followed by the 50 Nickel family. Can you supply monopole magnets? No, we don t, nor does anyone else, because they don t exist. All magnets must have at least two poles. Disc, cylinder, and sphere shapes definitely cannot be manufactured this way. Rings magnetized this way are referred to as "radially magnetized", but it is not currently possible to manufacture neodymium ring magnets this way.

We are working on it, however. Does stacking magnets together make them stronger? Yes, two or more magnets stacked together will behave exactly like a single magnet of the combined size. How is the strength of a magnet measured? Gaussmeters are used to measure the magnetic field density at the surface of the magnet. This is referred to as the surface field and is measured in Gauss or Tesla. Pull Force Testers are used to test the holding force of a magnet that is in contact with a flat steel plate.

Pull forces are measured in pounds or kilograms. All of the pull force values we specify have been tested in our laboratory. We test these magnets in two different configurations. Case 1 is the maximum pull force generated between a single magnet and a thick, ground, flat steel plate. Case 2 is the maximum pull force generated with a single magnet sandwiched between two thick, ground, flat steel plates.

Case 3 is the maximum pull force generated on a magnet attracted to another magnet of the same type. The values are an average value for five samples of each magnet. A digital force gauge records the tensile force on the magnet. The plates are pulled apart until the magnet disconnects from one of the plates. The peak value is recorded as the "pull force". If using steel that is thinner, coated, or has an uneven or rusty surface, the effective pull force may be different than recorded in our lab.

I am using another online magnet pull force calculator. Most other online calculators are based on theoretical formulas, which are notoriously inaccurate, especially for very large or very small sizes. Our pull force and magnetic field density calculators can be found here: Will a magnet with a 20 lb pull force lift a 20 lb object? Because pull force values are tested under laboratory conditions, you probably won t achieve the same holding force under real world conditions.

The effective pull force is reduced by uneven contact with the metal surface, pulling in a direction that is not perpendicular to the steel, attaching to metal that is thinner than ideal, surface coatings, and other factors. Yes, we ve posted Demagnetization Curves for our most common Neodymium magnet grades right here. What does a magnetic field look like?

The traditional way of visualizing magnetic fields is to place a magnet near a surface covered with iron filings. If you already have some of our magnets, this is a good experiment to conduct! In the meantime, we ve created a series of images using Finite Element Analysis software, which can be viewed here. How do magnets really work? This is a very interesting question. It s actually a difficult question to answer well.

As the late, great physicist Richard Feynman once said, "How much of an explanation is enough to satisfy you? How do Magnets Work on YouTube. If you do want more details, this interesting video: How Special Relativity Makes Magnets Work has a great description about why an electromagnet is attracted to iron. How Do They Work? It addresses how permanent magnets with seemingly no current running through them can act magnetic.

Ironically, even with that incredible level of detail, at some point they still end up saying, " Why? No one knows.

    I can not participate now in discussion - it is very occupied. But I will be released - I will necessarily write that I think on this question.

    In my opinion you are not right. I am assured. I suggest it to discuss. Write to me in PM, we will talk.
