Frenergy MagnetsDISC Magnets
Qty: 100PCS OF MAGNETS ONLY
Product Code: D-D5H2-N50
Diameter: 5mm (0.197" in.)
Height: 2mm (0.0787" in.)
Coating: Nickel (Ni)
Magnetized Direction: Through height - 2mm
Theoretical Holding Force: ~0.721kgs
Surface Gauss: 4402 SMALL magnets !
Magnets rated holding force is when contacteddirectly againstmild steel 3mm thick or greater at horizontal position.
If you position the magnet sideway (vertically), you should divide the holding force amount by 3.This is due to the the influences of gravity and reduced friction.
Please note that magnetic strength will beweakerif the item you are attaching to isalloy, stainless steel, Colourbond steel, painted, oily, rusty or bumpy.
Also, if the ferrous item your attaching to is thin, the magnet will be weaker too, i.e. foil or sheet metal
If something in between the magnets and the surface your attaching to (i.e fabric), the pull strength also will be lesser.
Rare earth magnets are a special type of magnet. They are the worlds strongest type of magnet and are composed of Neodymium, Iron and Boron (NdFeB) elements. We sell magnets ranging from N35 to N52, also with various coatings. We were the first to offer BULK rare earth magnets on in Australia and we are still the CHEAPEST and the BEST!
Price Guarantee: All our competitors in Australia are more expensive than us for the same product. You can check our competition on or other websites and if you find a cheaper product we will beat it guaranteed.
Discounts: Bulk purchase >$200 attracts special discount. Please contact seller before checkout.
Custom Magnets: If you require a customsize please contact us.

Safety Notes about Neodymium Magnets:
- Handle magnets carefully. Neodymium magnets are strongly attracted and snap together quickly. Keep fingers and other body parts clear to avoid getting severely pinched.
- Keep magnets away from electronics. The strong magnetic fields of neodymium magnets can erase magnetic media like credit cards, magnetic I.D. cards, and video tapes. It can also damage electronics like TVs, VCRs, computer monitors, and other CRT displays.
- Keep magnets away from young children and pets. ALL MAGNETS we sold ARE NOT TOYS and pose a choking hazard and can cause internal damage if swallowed. Older children 13+ yr old should handle them only under adult supervision, and wearing proper safety equipment.
- Avoid use around people with pacemakers. The strong magnetic field of neodymium magnets can disrupt the operation of pacemakers and similar medical devices. Never use neodymium magnets near persons with these devices.
- Use the magnets gently. Neodymium magnets are more brittle than other types of magnets and can crack or chip. Do not try to machine (cut) them. To reduce the chance of chipping, avoid slamming them together. Eye protection should be worn if you are snapping them together at high speeds, as small shards may be launched at high speeds. Do not burn them; burning will create toxic fumes.
- Be patient when separating the magnets. If you need to separate neodymium magnets, they can usually be separated by hand, one at a time, by sliding the end magnet off the stack. If you cannot separate them this way, try using the edge of a table or a countertop. Place the magnets on a tabletop with one of the magnets hanging over the edge. Then, using your body weight, hold the stack of magnets on the table and push down with the palm of your hand on the magnet hanging over the edge. With a little work and practice, you should be able to slide the magnets apart. Just be careful that they do not snap back together, pinching you, once you have separated them.
- Wear eye protection. Neodymium magnets are brittle and may crack or shatter if they slam together, possibly launching magnet fragments at high speeds.
- Drilling and Machining. Neodymium magnets are by nature very hard and brittle. Drilling and machining is highly not recommended. Magnets will break and chip.
Magnetic Strength and Gauss: Magnetic strength and Gauss ratings can be confusing. Many companies advertise their magnets and magnetic products with the “internal gauss” rating which is very different from the actual “surface gauss”. The surface gauss is dependent on the N-rating, size and shape of magnet. We provide a magnetic force calculator to calculate holding force and gauss at our website. Just type “Frenergy” or “Magnetic Force Calculator” into a search engine like Google and find our website. We have provided the surface Gauss in the item description above and also further technical information in the tables below.
Coatings: We have supplied a Coating properties table below. Most of our magnets are nickel coated as this is the most durable and economical. Gold coatings are used primarily for direct skin contact to reduce the risk of skin irritation.
Types of magnets: There are 5 main types of magnets. Neodymium and Samarian Cobalt are permanent magnets which means they don't lose their magnetism over time like Alnico, Ceramic/Ferrite or Flexible rubber magnets. Neodymium are the strongest however most are rated below 100 degrees C. Some neodymium magnets can tolerate up to 150 degrees C. Samarian Cobalt are the most expensive as shown in the cost comparison and have both high temperature and high strength properties. Ceramic/Ferrite and flexible rubber magnets are the least expensive and also have low magnetic force.
