there are many references to nickel and zinc in ferrites. Are these wrong?
rai69:
"Today, they are the most commonly used magnets in radios. The maximum magnetic field B is about 0.35 tesla and the magnetic field strength H is about 30 to 160 kiloampere turns per meter (400 to 2000 oersteds). (Hill 2006)"
Sorry but in my opinion these must be old informations; with actual (2007) numeric values it would be: The maximum magnetic field B is about 0.43 tesla and the magnetic field strength H is about 30 to 360 kiloampere turns per meter (not doped)and B is about 0,44 tesla, H is about 380 kA/m for doped materials.
Maybe, somebody with better command of English than me could change this in the articel.

should Chemie.de get a mention, as the majority of this information was ripped off, word for word, from their site? —Preceding unsigned comment added by 193.195.77.146 (talk) 10:36, 4 January 2008 (UTC)
"They are the most commonly used magnets in radios." Huh? Where, exactly? In the speakers? Needs clarification. 209.145.162.138 (talk) 18:03, 14 May 2008 (UTC)bplipschitz
