Ferrite Magnets: Iron Boron Ceramic Magnet errite magnets are ceramics that are stronger by weight than steel or Alnico equivalents but less so than neodymium magnets. Ferrite magnets are also good for doing repulsion and attraction experiments since some of the rare earth magnets may be too strong and steel bar magnets will demagnetize. The plain ferrites shown below are all magnetized through their thickness. www.indigo.com /magnets/ferrite-magnets.html   (228 words)

Ferrite (magnet) - Wikipedia, the free encyclopedia Ferrites are ferromagnetic ceramic materials, compounds of iron, boron and barium or strontium or molybdenum. Ferrite cores are used in electronic inductors, transformers, and electromagnets where the high electrical resistance of the ferrite leads to very low eddy current losses. Ferrite particles are also used as a component of radar-absorbing materials used in stealth aircraft and in the expensive absorption tiles lining the rooms used for electromagnetic compatibility measurements. en.wikipedia.org /wiki/Ferrite_(magnet)   (269 words)

Rare earth magnets for fun and profit Magnetic field strength drops off as the inverse cube of the distance from the magnet, too; get twice as far away and the field strength drops by a factor of about eight. The stronger the magnet and the more metal there is (the base of a chunky CPU cooler is an excellent candidate for this experiment, and I've got a few of those kicking around...), the stronger the "syrupy" feeling you'll get. You'll find magnetic dampers on laboratory balances, for instance; a simple aluminium or copper tag on the end of the balance arm, moving between two strong magnets attached to the balance's frame, is the perfect way to stop the balance from oscillating for ages before settling on a reading. www.dansdata.com /magnets.htm#ff   (5513 words)

Arnold - Hard Ferrite Magnets Even though they exhibit low energy (compared with other permanent magnet materials) and are relatively brittle and hard, ferrite magnets have won wide acceptance due to their good resistance to demagnetization, excellent corrosion resistance and low price per pound. The raw materials used to produce ferrite magnets are strontium carbonate and iron oxide both of which are readily available and low in cost. Ferrite magnets are formed by compaction in dedicated, multi-cavity dies followed by sintering in high temperature furnaces. www.arnoldmagnetics.com /products/ferrite   (401 words)

WONDERMAGNET.COM - NdFeB Magnets, Magnet Wire, Books, Weird Science, Needful Things This is because the size and shape of a magnet and the material behind it (such as iron) have a large effect on the measured field strength at the surface, as does the exact location at which it measured. The north pole of a magnet is the pole that aligns itself with geographic north. Elementary physics states that the magnetic field of a magnetic dipole is approximately proportional to the inverse cube of the distance from the dipole. www.wondermagnet.com /magfaq.html   (4043 words)

diyAudio Forums - Nd doping of ferrite magnet drivers Tuning an off-the-shelf driver that comes with a ferrite magnet and has no or insufficient short-circuit sleeving and testing for distortion reduction has been a thing that I have wanted to to for a while. Considering that modern Nd magnets have 10x higher flux density than ferrite and that most driver designs operate the iron at 70-90% of saturation flux, replacing only 1/10 of the ferrite with Nd would suffice to drive the iron well into saturation. Ferrite is hard like ceramic so I expect you would have to use some kind of small grinding wheel. www.diyaudio.com /forums/showthread.php?postid=431299   (418 words)

Sell Barium & Strontium Ferrite Magnet When designing the ferrite magnets for a particular application, primary consideration should be given to its shape limitation due to the powder metallurgical manufacturing process and the temperature dependence of ferrite materials. Isotropic ferrite magnets are not oriented and can be magnetized in any direction; anisotropic ferrite magnets are different, they are all oriented in the manufacturing direction, and should be magnetized in the direction of orientation. Ferrite magnets are sintered permanent magnets composed of Barium or Strontium Ferrite. amc.en.alibaba.com /offerdetail/52312220/Sell_Barium_amp_Strontium_Ferrite_Magnet.html?src=rss   (423 words)

What types of magnets are there?   (Site not responding. Last check: 2007-10-15) Temporary magnets are those which act like a permanent magnet when they are within a strong magnetic field, but lose their magnetism when the magnetic field disappears. Both the Neodymium Iron Boron and the Samarium Cobalt magnets are generally known as rare earth magnets since their compounds come from the rare earth or Lanthanide series of the periodic table of the elements. The flexible magnets we use are a type of ceramic magnet, with the magnetic powders fixed in a flexible binder. my.execpc.com /~rhoadley/magtypes.htm   (1524 words)
