similar to that surrounding a bar magnet. Magnets are also surrounded by a similar three-dimensional field. This can be "seen" in two dimensions if iron filings are sprinkled on a sheet of paper ...

At room temperature, a pure bar of neodymium wouldn’t be ... The most common rare-earth magnet alloy, a combination of iron, neodymium, and boron, has a Curie temperature in the range of 300-400 ...

Magnets are made from magnetic metals – iron, nickel and cobalt. These are the only pure metals that can be turned into a magnet. If these metals have not been turned into a permanent magnet ...

It’s composed predominantly of iron and nickel which are ... As you may recall from Physics 101, a changing magnetic field (like when you slide a bar magnet through a copper coil) induces an electric ...

Only certain materials, such as iron, feel a magnetic force. Permanent magnets can come in lots of different shapes and sizes. Bar magnets and horseshoe magnets are two of the most common shapes ...
