How to re-magnetise an old magnet ? Re-magnetise Old Magnet Even if your magnet is kept in top condition, it can still become demagnetised during its lifetime. An example of this is a samarium cobalt magnet which has been shown to naturally lose 1% of its magnetic capabilities over a period of 10 years. [...]
Avoid Demagnetising Magnet Demagnetisation is the process whereby a magnet loses all of its magnetic properties. The magnet most prone to demagnetisation is the ferrite magnet due to the alloy it is made of, however all magnets can be demagnetised. To avoid demagnetising your magnet, follow these guidelines: Separating your magnets Make sure you separate [...]
Here are some suggestions and recommendations for the installation and functionality testing to Use Electromagnetic Locks: electromagnetic-lock-feature-illustration Use Electromagnetic Locks - The electromagnetic lock requires a face to face fitting as shown in the illustration. Otherwise, the holding force will decrease (direction of hydraulic press pull must be collinear). electromagnetic-lock-and-armature-plate Install [...]
Shipping Magnets by Air Shipping Magnets by Air: For air shipment purposes, magnets are considered "dangerous goods" and the International Air Transport Association's (IATA) Dangerous Goods Regulations (DGR) must be followed. shipping-magnets-by-air In order for HSMAG magnets to be shipped by air: Flux measurements of all packages containing magnets must measure less than [...]
DC Motor, Brushed DC Motors, Brushless DC Motors DC Motor - There are many motor choices on the market today, from heavy-duty AC motors to tiny DC brushless and stepper motors. To select the right motor for the application, users must have a full understanding of the application parameters, including power, speed, torque, physical size, efficiency, lifetime [...]
Magnets, with the right maintenance and care, can last indefinitely. For information on how to look after your magnet, here are a few tips: Storage Storing a magnet correctly is one of the most important ways in which you can give your magnet a long life. All magnets can be stored together in one place, [...]
Demagnetization is the reduction or elimination of magnetization. One way to do this is to heat the object above its Curie temperature, where thermal fluctuations have enough energy to overcome exchange interactions, the source of ferromagnetic order, and destroy that order. Another way is to pull it out of an electric coil with alternating current [...]
Magnetic Olive, Magnetic Snake Eggs, Rattlesnake Eggs, Buzz Magnet, Magnetic Sound Magnetic Olive Toss the Magnetic Olive into the air. The two hematite magnets fly and collide, wrestling for equilibrium in a clattering, buzzing, Cicada sounding collision until they land at rest, centered and quiet in your cupped hands. A pair of powerful ellipsoidal hematite magnets, [...]
Magnetic Base Clip Installation for Precast Construction Eliminate caulking on your metal casting beds with Victory Bear's Magnetic Base Clip and Rustication system. • Step 1 – Place the special Base Clip on the casting bed according to the planned reveal layout. • Step 2 – Secure the Base Clip to the casting bed by [...]
The strength of a magnet is indicated by either its pull force or its magnetic field strength. A magnet's strength is always stated in the product information for a magnet, however manufacturers use the following methods to discern this: Pull force The pull force of a magnet is the amount of force required to pull [...]
It is possible to demagnetise a Neodymium magnet by applying an external magnetic field in a direction opposite to the direction of magnetisation (DoM) of the NdFeB magnet. The extent of demagnetisation is a function of the total magnetic circuit (and hence the Intrinsic working point), the temperature (and hence the actual BH curve shape [...]
For note, the effects of temperature and external demagnetising fields are easiest to calculate on NdFeB magnets that may be demagnetised as a result of such exposure if cgs units are used (Gauss, Tesla, MGOe) as cgs units allow faster production of new BH curves. When a new Intrinsic BH curve for Neodymium has been [...]
Your Dead Hard Drive You can turn your old, dead hard drive into a stud finder that works better on plaster walls than electronic stud finders, and can work better on dry wall, too. What better use is there for that expensive hard drive than turning it into a humble stud finder? I can’t think [...]
SENSOR MAGNET SELECTION Magnetic field profiles example Magnets, electromagnets and solenoids could all be used to trigger magnetic sensors such as Reed Switches and Hall Effect devices. The choice of magnet is determined by the actual application and the environment of the application. Temperature, distance and location of the magnet, presence of other [...]
Here HSMAG tell you : How to use a hand-held magnetic sweepers Lift up hand-held magnetic sweeper Step 1 - Lift up hand-held magnetic sweeper Hold the magnet by the handle and lift it up to a comfortable height. The best height would be 4" from the surface you are sweeping. Step 2 [...]
Magnets measured and graded for strength, quality, etc. here you can learn about it, thanks. Magnets measured and graded Magnet Strength Measurements (B)--The units for measuring the field strength (flux density) of a magnet are Gauss or Tesla. 1 Tesla = 10,000 Gauss. The Earth's magnetic field is on the order of 1 [...]

Purchasing Magnetic Tube Separation, Buy Magnetic Tubes, Magnetic Tube Separation mentioned methods how-magnetic-tube-works How magnetic tubes works A magnetic tube made of a stainless steel tube, polar plates,end-plugs, and permanent magnets. The higher the surface gauss of the tube, the higher the price. As the permanent magnets being the most expensive parts, we will look [...]
a through hole pot magnet A pot magnet works by attaching itself to ferromagnetic materials with the help of its magnetic field, or to non-ferromagnetic materials with the help of fittings (such as studs and threaded holes) on the top of its steel shell. steel shell on a pot magnet The [...]
magnetic-propulsion-space-pixabay With help from magnets, we may be able to explore farther and deeper into the final frontier than ever before. This may sound like science fiction, but scientists are already experimenting with electromagnetic propulsion as a possible alternative to chemical launches. So, how does electromagnetic propulsion work? When an electromagnet is cooled [...]
A magnet is any object that produces its own magnetic field. The magnet strength of these objects can vary from imperceptibly weak fields to incredibly strong fields, depending on a number of characteristics. Magnets can be classed into two distinct groups: permanent magnets and electromagnets, and non-magnets can be defined as either ferromagnetic, paramagnetic, or [...]
