If you re-magnetize it with a coil wrapped around it, the magnetization lines will pretty much follow the S shape, and the poles will be at the ends. However, if it’s made of some ordinary metal you probably have to heat it up to deform it, and it’s likely to demagnetize when it’s hot. If you start with a simple bar magnet, and gradually deform it into an S shape, you might think that the magnetization lines will just twist along with the magnet.
That depends on when it is magnetized, and how. Kind) has an electromagnet inside to steer the electron beams across Pole or just an S pole - there will always be two!).Įven your television (if its not one of the new plasma or LCD Still stick well to the door (you cant cut it up so theres only a N With the door, or if the magnet is cut up in pieces, the pieces will Stick well even if only part of the refrigerator magnet is in contact North and South poles so the magnetic field lines can leave the magnet,įlow through your refrigerator door and come back in again so it will You can make sextupoles and octupoles with three and fourĮach of the North and South poles. They are used to focus beams of high energy These tend to be square on the outside with alternating N and S poles A simple extension is a "quadrupole", with two of each. Some magnets have more than one North pole and more than one Other magnets can be made in other shapes to accomplish other Some of these may not be easy to understand except for readers whove The topic, here are some more thoughts about strange magnet shapes. That may pretty much answer your question, but as long as were on Of amperes of electrical current through the wire - no resistance, no Superconductors are chosen to reduce the cost of flowing the thousands Good yet at building wires out of high-temperature superconductors). Whole thing has to be kept at liquid helium temperatures (were not so The wire is often superconducting, so the They usually consist of many turns of very thick wire around in Very large magnetsĪre used in high-energy physics experiments and can be several stories
The strongestĪnd largest magnets ever made are electromagnets. Through a coiled wire, it will produce a magnetic field. Usually involves heating up the magnet and then cooling it off with an Plastic with iron powder mixed in, poured on a flat surface, and thenĬut into rectangular (or other) shapes. Refrigerator magnets are probably made of molten Some small ones may be stamped out of sheet The shape of a magnet determines how the magneticįield lines are arranged outside of the magnet, which affects what theĪll of the methods you mention have been and continue to be used Magnets come in all shapes and sizes, and are used for a great Reasons, and many of us never get tired of experimenting with them. Very nice question! Magnets are really a lot of fun for a lot of
