I have contacted to a company makes field coil magnet and decided to convert AlNiCo 288 to Field Coil Magnet.我和一个制造励磁磁铁的公司接触过后，决定把288的钴磁改装成励磁磁铁。
The 288 field coil sounds similar to AlNiCo but extremely smoother, therefore warmer and does not kill your ear as of 28励磁288的声音和钴磁类似，但是，更加顺滑，因此更加温暖，并且在大声鸣放时不会让你耳朵刺痛。
