What happens if a magnet breaks

Mike W. Why would it be difficult for a material to have trouble flipping around its domains? Can you specify what a domain is? First, a ferromagnetic domain is a region in which the magnetism of the individual particles mostly lines up in the same direction.

The reason that the domains can stay stuck for a long time is that certain directions are easier lower energy than others. It's always equally easy to point one direction or its opposite, but the intermediate directions can require more energy. It can take a very rare event for a domain in a "hard" magnet to get enough energy to flip through that intermediate high-energy state. In a "soft" magnet like pure iron the energy required can be quite low, so the domains don't stay stuck. Simple bar magnets introduce the concept of a field.

The way that some materials can For 8 Resources. There's a good chance you could improve your teaching if you were to try these strategies. Teaching Guidance Electromagnetic machines are very common. The number of turns of wire does determine the strength of an electromagnet. There is a simple experiment to prove that to yourself. Wrap iron nails with different amounts of thin, insulated wire, and connect them, one at a time to a small battery.

There are several ways to measure the strength of these different electromagnets. There are meters called gauss meters. You just place the gauss meter probe in the magnetic field and it will tell you the strength of the field at that point. I'm almost sure that is more than you can afford with your allowance. A reasonable method to measure magnet strength is to simply count how many of a small item that each magnet will pick up.

When you cut a bar magnet into two pieces, the magnetic moments are still aligned as they originally were. If cut in two, they will still exhibit the properties of a standard dipole magnet. The magnetic field generated by any magnet is always strongest at either pole. The magnetic force is equally as strong at both the north and south pole. The two individuals magnets do have opposite polarized ends on each magnet, but at the break point the ends are opposite to each-other, so they attract and connect.

Answer 2: The strongest magnet ever build is foot tall and weights 34 tons. It was built in a research lab in Tallahassee and it produces a magnetic field of at least 45 Tesla. To understand how powerful this is you have to know that the strength of a magnetic field is measured in Gauss G or Tesla T.
