Q: What creates magnetic forces?: Moving electrons create magnetic fields. These electrons can be moving in a wire: which is the way that electromagnets work. Or they can be in their electron shells in atoms and molecules. That is how 'permanent magnets' work. Most materials have these magnetic fields from the electrons in their atomic structure pointing in random directions. There are only a few elements and a few other compounds and alloys that have the capacity to have these tiny magnetic fields align to one direction. When they are pointing in random directions they sort of cancel each other out, But when they are aligned, they sort of add and become what we know as a magnet.

Q: I got assigned a EM crossword in science for homework and I can‘t find some of the answers in the book and google is coming up deserted with correct answers. Pease help with some of the answers?One of the three materials that are magnetic (6 letters)Increase the number of these to make electromagnetics stronger (5 letters)Used to measure the potential difference in a circuit (9 letters)Used to measure to flow the electrons (7 letters)Potential difference in a circuit (7 letters)Type of electricity when charges are sitting on the surface (6 letters)The type of pipe in the forensics crime (5 letters)Do not tell me to search on google because I aready did that.Thanks!: One of the three materials that are magnetic (6 letters) ???????COBALT or NICKEL ———————————————— edit Some guesses: Increase the number of these to make electromagnetics stronger (5 letters) ???????VOLTS? COILS? Type of electricity when charges are sitting on the surface (6 letters) ???????STATIC? The type of pipe in the forensics crime (5 letters) . any more details?

Q: I need it for a science essay. please help: Sideshow bob is right. Supercondutors will not allow a magnetic field to penetrate. If the magnetic field is strong enough, it will force the superconductor to stop superconducting and then the field will penetrate. Research Eddy currents.

Q: ok this has been bugging me for a while now. if supposedly venus, earth, and mars had/have a molten core then why is earth the only one with a magnetic field. does it have something to do with plate tectonics and the moon.: Earth is the only terrestrial planet with a significant magnetic field because it is the only one that has all the ingredients: a conducting liquid, convection, and rotation. Venus, because of its lack of plate tectonics, lacks convection. Mars lacks a conducting liquid because its core solidified.

Q: Why do the radio antenna bar soft magnetic material, rather than by the hard magnetic materials: The radio antenna bar is to magnify the magnetoelectric conversion function, the process of magnetoelectric conversion in the direction is changing, soft magnetic material has no remanence (or weak)

Q: I‘m stuck on my Physics homework and I need to know the answer asap. So can anybody tell me the difference between hard and soft magnetic materials?: Hard magnets, such as steel, are magnetised, but afterwards take a lot of work to de-magnetise. They're good for making permanent magnets, for example. Soft magnets are the opposite. With an example being iron, they are magnetised, but easily lost their magnetism, be it through vibration or any other means. These are best for things that only need to be magnetised at certain points, eg magnetic fuse/trip switch.

Q: What is magnetic coercivity;give examples of it in at least 1 one experiment?: In materials science, the coercivity, also called the coercive field, of a ferromagnetic material is the intensity of the applied magnetic field required to reduce the magnetization of that material to zero after the magnetization of the sample has been driven to saturation. Coercivity is usually measured in oersted or ampere/meter units and is denoted HC. Coercivity measures the resistance of a ferromagnetic material to becoming demagnetized. Coercivity can be measured using a B-H Analyzer. Materials with high coercivity are called hard ferromagnetic materials, and are used to make permanent magnets. Permanent magnets find application in electric motors, magnetic recording media (e.g. hard drives, floppy disks, or magnetic tape) and magnetic separation. A material with a low coercivity is said to be soft and may be used in microwave devices, magnetic shielding, transformers, or recording heads. As for an experiment, it is used in magnetic information storage. The main challenge in designing magnetic information storage media is to retain the magnetization of the medium despite thermal fluctuations caused by the superparamagnetic limit. If the thermal energy is too high, there may be enough energy to reverse the magnetization in a region of the medium, destroying the data stored there. The energy required to reverse the magnetization of a magnetic region is proportional to the size of the magnetic region and the magnetic coercivity of the material. The larger the magnetic region is and the higher the magnetic coercivity of the material, the more stable the medium is. There is a minimum size for a magnetic region at a given temperature and coercivity. If it is any smaller it is likely to be spontaneously de-magnetized by local thermal fluctuations. Perpendicular recording uses higher coercivity material because the head's write field penetrates the medium more efficiently in the perpendicular geometry. Hope this helps!

Q: At what temperature does a magnet lose its magnetic power and why?: For each material of magnet, there is a Curie temperature, or temperature at which the heat will destroy the polarization of the material, causing it to loses its magnetic properties. These former magnets can be re-magnetized in the same way the alloys are magnetized for the first time. Temperatures lower than the Curie temperature can weaken a magnet, but the magnetism will usually return to full strength when it is returned to normal temperatures. In the case of rocks and minerals, remanent magnetism appears below the Curie point—about 570° C (1,060° F) for the common magnetic mineral magnetite.

Q: How long will a magnet last if it is opposed by a magnetic force equal to its own?: Go to the dealer, have them inspect it.

Q: It is made from rocky materials and has an iron core and the tidal heating keeps everything from freezing. So shouldnt it have a magnetic field?: two reasons. Io has a sesquisulfide (iron sulfide, ferric sulfide) core, which is not a metal. it's a compound. a world has to have a metallic core to generate a magnetic field. the core also doesn't spin rapidly, while the terrestrial planets' cores do (except for mars, which has a metallic liquid core that doesn't spin, and so it doesn't have a magnetic field). hope this helps! :) cedric
