You are buying 1 rare earth magnets.

We supply many of the MAJOR Universities in Australia including, RMIT, Griffith Uni, Melbourne Uni, Charles Sturt Uni, James Cook Uni, QUT. These universities have come to us for their magnets because we have them manufactured from one of the oldest and most respected companies that make this type of magnet.

Also we have supplied some of Australia's most innovative companies in the development of new products, a plethora of craft stores, backyard experimentalists and the hobbyists alike

Explanation of coatings:

Coatings do not affect the magnetic performance but should be chosen for the magnets intended use.

• Nickel - silver shiny finish, good corrosive properties, used for industrial applications, crafts, experiments, science, very durable coating. Direct skin applications over time may irritate.
• Gold - gold coating over nickel, direct skin applications, low durability
• Epoxy - plastic like coating, excellent corrosion properties, least durable, various colours
• Tin - shiny and dull grey spirals, not a common coating
• Zinc - dull grey in colour, higher corrosion compared to nickel

**Please note: Unless your using these magnets for very technical scientific purposes you cant tell the difference between N42 and say N45 for magnets of the same size and quality. Some Sellers selling similar items claim differences of 20%, however this is very misleading. The difference between N42 and N44 is less than 3%. Magnetic performance also depends on the quality of materials and manufacturing process. When comparing magnets, you need to look at the amount of mass each magnet has, not just the Gauss rating, rule of thumb: The bigger the magnet, the stronger it is. See table below when comparing magnets of the same size:

Max Energy Product	Residual Induction	Coercive Force	Intrinsic Coercive Force
(BH)max	Br	Hc	Hci
(MGOe)	(gauss)	(oersteds)	(oersteds)
32	11600	11100	31000
34	11960	11500	22250
36	12200	11700	26000
38	12400	12000	23000
40	12900	12400	23000
42	13100	12700	15000
44	13500	13000	15000
48	13750	10300	11000
50	14100	10300	11000

• There is no such thing as a single or monopole magnet......yet
• If you apply heat to magnets they WILL lose some of their strength
• There is no indication that magnetic fields harm the body, in fact many people believe magnetic therapy is very beneficial.

These magnets are very versatile and can be used for anything including science experiments, art and craft accessories, engineering, hobbies, jewellery, magnetic therapy, or anything you choose. Useful for any purpose where you need to join bits together. Be careful of the larger magnets, they BITE!! J

If you require a custom size please email me. We have disc, ring, block, cube, sphere, cylinders, singing magnets, health magnets and patches, magnetic tools, and magnetic toys and more. We are the magnet specialists.

WE WILL NOT BE BEATEN ON PRICE, SERVICE OR SOUND ADVICE
