NdFeB has the best performance among the rear-earth permanent
magnets . It is the alloy magnet of Neodymium(Nd) , Iron(Fe) ,
Boron(B) and some other microelements , produced through the Power
Metallurgy technology , NdFeB is called the “king of magnet” due to
its strong power(high residual induction , coercive and energy
product) , competitive price and great machinability.
Magnetization direction options:
- Magnetic recording media: VHS tapes contain a reel of magnetic
tape. The information that makes up the video and sound is encoded
on the magnetic coating on the tape. Common audio cassettes also
rely on magnetic tape. Similarly, in computers, floppy disks and
hard disks record data on a thin magnetic coating.
- Credit, debit, and automatic teller machine cards: All of these
cards have a magnetic strip on one side. This strip encodes the
information to contact an individual's financial institution and
connect with their account(s).
- Common televisions and computer monitors: TV and computer screens
containing a cathode ray tube employ an electromagnet to guide
electrons to the screen. Plasma screens andLCDs use different
- Speakers and microphones: Most speakers employ a permanent magnet
and a current-carrying coil to convert electric energy (the signal)
into mechanical energy (movement that creates the sound). The coil
is wrapped around a bobbin attached to the speaker cone and carries
the signal as changing current that interacts with the field of the
permanent magnet. The voice coilfeels a magnetic force and in
response, moves the cone and pressurizes the neighboring air, thus
generating sound. Dynamic microphones employ the same concept, but
in reverse. A microphone has a diaphragm or membrane attached to a
coil of wire. The coil rests inside a specially shaped magnet. When
sound vibrates the membrane, the coil is vibrated as well. As the
coil moves through the magnetic field, a voltage is induced across
the coil. This voltage drives a current in the wire that is
characteristic of the original sound.
