Coating
Coating prevents superstrong magnets from corrosion and wear as well as their longevity. Often they come in multiple layers of nickel-copper-nickel, zinc, or epoxy.
Magnetic strength
This measures the strength of the magnetic field at a given distance from the magnet, measured in gauss or teslas. Typical range is 1,000 - 15,000 gauss, or 0.1 - 1.5 tesla.
Magnetic flux density
This is the measure of the amount of magnetism per unit area in the material. Common density is 1.2 - 1.5 tesla.
Maximum working temperature
Temperature above which the magnet loses its magnetisation or strength. Common maximum temperature is 80C for N42, 150C for N52, and 180C for H.
Installation depends on the application, but some basic rules apply in most cases.
Strong fridge magnets have varying usages depending on their strength and size. For example, larger industrial magnets, such as super magnets for lifting, are used in construction sites to handle heavy iron or steel loads. In contrast, small yet strong magnets like neodymium are used in home kitchens to hold knives in place.
Magnetic force exertion
The first step in using super magnets is identifying the metallic target. This could be any iron-based material, including tools, in the workshop or equipment.
Positioning the magnet
Bring the magnet close to the target item without allowing it contact. A strong magnet will attract object within its range of attraction, pulling it towards itself.
Attraction
Once the magnet is in range, the target metal will stick to its face. Ensure the magnetic surface is clean to allow full contact with the target material. Any debris will reduce magnetic attraction, making it weaker.
Removing the magnet
To separate the magnet from the target, carefully pull it straight away so there is no chance of it snapping shut and pinching fingers. If attraction is very strong, slide the magnet off to lessen effort needed. It is also advised to use protective gloves all the time when handling strong magnets.
Regular cleaning: This helps the magnet maintain its attractive properties. Use a soft, dry cloth to wipe off any dust or debris that might accumulate on the magnet's surface. If the magnet is exposed to corrosive materials, consider using a mild detergent with water to clean it, ensuring it's completely dry afterward.
Check for chipping: For coated magnets, regularly inspect the coating for any signs of chipping or peeling. If the magnet is exposed to harsh chemicals or frequent wear, the coating might need replacement, especially if corrosion of the magnet occurs.
Storage conditions: Do the storage in a dry place where the super magnets are not exposed to extreme temperatures. These factors affect the magnetic strength. Use spacer blocks made of steel to prevent two neodymium magnets from coming into direct contact with each other and elimiantes the risk of cracking or chipping.
Material composition
The strength and durability of neodymium magnets largely depend on the quality of materials used in their composition, i.e. alloying neodymium, iron, and boron. They are widely known for their exceptional resistance to corrosion and demagnetization, which is key in making them long-lasting.
Magnetization process
Quality super magnets undergo intense magnetization as high electric currents are passed through them. This ensures even distribution of magnetic fields and, therefore, optimal strength in the magnets for effective performance.
Coatings
Super magnets have multiple-layer coatings, such as nickel and copper; they lend them to durability and protection against environmental factors. These coatings guard against rust and wear, thus increasing their longevity when exposed to moisture and air.
Manufacturing standards
Super magnets are produced in controlled environments by professionals who understand magnet fabrication. Quality control measures include testing for strength, coating integrity, and dimensional accuracy to ensure super magnets meet required performance standards.
Temperature resistance
Quality neodymium magnets maintain their strength even under extreme conditions. Super magnets retain their properties at high or low temperatures, unlike many magnets that lose their magnetic properties when exposed to extreme temperatures.
Follow these guidelines to check for quality, clean, maintain, and store strong fridge magnets in the right way.
Visual inspection: Check for obvious signs like cracks, chips, or corrosion. Also, check the coating to ensure there are no peelings or rusts, as this might weaken the magnet.
Magnetic strength test: Bring the magnet close to a metallic object, say a screwdriver, and see how far it can pull it. A quality magnet will easily attract a heavier object without much effort.
Coating integrity check: Examine the magnet's coating for wear or unsheathing. Exposure to moisture or abrasion may cause corrosion, further damaging the magnet.
Magnetic field check: Hold small metallic items close to the magnet to see if they stick. This helps to test its magnetic field.
Cleaning: Soak rusted adhesive magnets in a mixture of water and vinegar for about 10 - 20 minutes, and then scrub with a soft brush.
Antirust application: After cleaning, apply cooking oil or petroleum jelly over the magnet surface to prevent future rusting.
Proper storage: Keep magnets in a dry and cool location away from direct sunlight; avoid stacking unprotected magnets as this might lead to chipping.
Use spacers: Use steel spacer blocks between magnets while storing them to avoid direct contact; these blocks help in preventing crack or chip.
Check for re-rusting: Periodically check to see if the magnet has started rusting again, and repeat the oiling process when needed.
