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).
Magnets are used extensively in high energy and nuclear physics. We use some of the most powerful magnets in the world and certainly some of the coldest. Ok, to answer your question. Yes, I know what an electromagnet is. I have to assume you want to know a little more than that. An electromagnet is a magnet that is created when electricity flows through a conductor. The magnetic field goes around the conductor. The typical way electromagnets are built is to wrap many coils of wire around a ferromagnetic core (almost always iron).
