COW MAGNETS . What are they? Cow magnets are popular with dairy farmers and veterinarians to help prevent Hardware Disease in their cattle. While grazing, cows eat everything from grass and dirt to nails, staples and bits of bailing wire (referred to as tramp iron).
In my experience, the magnets used in speakers ARE regular magnets, they have a magnetic field even in absence of the electrical signal, but without the coil of wire, there can be no change in that field when the electricity is passed to the speaker. The coil is what turns the regular magnet into an electromagnet.here is an electromagnet attatched to the diaphragm. When current flows through the coil one way it becomes a magnet. since there is a permanent magnet behind the coil, the coil is pulled toward the magnet.
