What Are Magnet Used For?

Hard magnetic materials is ferrite materials which not easy demagnetization after the magnetization and will keep the magnetic characteristic for a long-term , also known as permanent magnetic material. The hard magnetic ferrite crystal structure are generally hexagonal stone-magnetic lead, is
typical of barium ferrite BaFe. This material has better performance, lower cost, not only can be
used as telecommunications devices such as audio, telephone and various instruments of the magnets,
but in the medical, biological and printing show that such areas have been applied. Hard magnetic
materials used to produce permanent magnets, the magnets of the speaker and the electronic circuit
memory components and etc.

This is a question I¡¯ll let you answer. There are hundreds and hundreds of uses which you will discover here at ''Magnet Man'' and in the links. Yes, some are used to hold the family¡¯s schedule and photos onto the refrigerator door, but that is just one use for magnets. Magnets were first put to use to help navigate since they would always point in a North / South direction, no matter what the weather was. Daniel Boone once said, ''I can¡¯t say I was ever lost, but I was bewildered once for three days.'' Perhaps if he had a compass, his bewilderment would have only lasted a few hours!

For the most part, magnets are used to hold, separate, control, convey and elevate products and to convert electrical energy into mechanical energy or convert mechanical energy into electrical energy.

Some more unusual uses for magnetics are:
refrigeration (see also Patent #4107935)
bending an electron beam or proton beam in a synchrotron
