Ferrite magnets are ceramics made primarily from iron and boron with a small amount of strontium. By weight they are stronger than steel or Alnico equivalents but less so than neodymium magnets. Like all ceramics, they are quite brittle & will easily break if dropped onto a hard surface. They are the most economical for their strength.
Can anyone comment on the truth as to why JBL dropped the AlNiCo magnet and went into production with the ferrite magnets?
Cost or greater magnet strength w/less distoration?
JBL Marketing seemed to focus on the later...
What was the JBL Development / Engineering scoop?
