Qty: 1 PIECE OF MAGNET ONLY Type: Neodymium Product Code. Diameter: 50mm 1.968 in. Height: 25mm 0.984 in.Magnetized Direction: Through height - 25mm. Theoretical Holding Force: 96.56kg each. Magnets rated holding force is when contacted directly against. Mild 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 be. If the item you are attaching to is alloy, 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. 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.

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.
It can also damage electronics like TVs, VCRs, computer monitors, and other CRT displays. Keep magnets away from young children and pets. 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. 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. Neodymium magnets are brittle and may crack or shatter if they slam together, possibly launching magnet fragments at high speeds. Neodymium magnets are by nature very hard and brittle. Drilling and machining is highly not recommended.
Magnets will break and chip. Be careful of the larger magnets, they BITE! Magnetic Strength and Gauss: Magnetic strength and Gauss ratings can be confusing. 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. You can make a direct deposit to our Australian bank. Domestic and International deliveries times are as follows.
This time frame is not guaranteed. Please allow these times before contacting us. We try to be very efficient and provide excellent service. Please see feedback from our customers in the last few weeks.This is important and ensures you are happy with our terms. We want your shopping experience to be a happy one and wish to avoid any complications later on. Out of Stock: In the rare event that we become out of stock of a particular item. It is a legal requirement. Items must be paid for within 5 days. Feedback: We will leave feedback for our customers and appreciate you leaving feedback for us. It lets others know what your experience was like with us and helps our business. Faulty Items: All products are individually inspected before being dispatched, to ensure items are sent out in perfect condition. In the unlikely event that a product is faulty, please return it to us within 7 days of receipt in its original condition.
We can spot the difference between a faulty item and a mishandled item, so please be careful when using the magnets and don't let them smash together, IT WILL CHIP AND BREAK THEM. We will not be held liable for any misuse of our products or failure to follow the instructions below. To clean magnets, clean with soapy water and damp cloth, rinse cloth then wipe magnets again. Our magnets are very powerful. The larger magnets can quickly snap together.
Please use caution and keep fingers and other body parts well clear of separated magnets. If using our magnets for medical purposes and health benefits, please consult your doctor. Our magnets should not be used by children to avoid risk of accidental swallowing or injury. Do not cut or grind the magnets as the magnetic material is explosive.To separate magnets, carefully slide them apart instead of attempting to pull them apart. Larger magnets may require special tools to separate and to hold them in place. Keep larger magnets more than 30cm (1 foot) away from each other to avoid the risk of them smashing together. If not handled correctly any size magnet may break, crack, chip or shatter. Keep magnets away more than 30cm (1 foot) away from credit cards, software, or any other magnetic storage media. The strong magnets can wipe the information clear. The item "1x Super Powerful Rare Earth Disc Magnet 50mm x 25mm N45 Neodymium Heavy Duty" is in sale since Tuesday, January 7, 2014.
