Q: How to choose high frequency transformer magnetic material?: High frequency transformer is more than the working frequency of intermediate frequency (10kHz) power transformer, mainly used for high frequency switching power transformer in high-frequency switching power supply, but also for the high frequency inverter transformer and high frequency inverter in high frequency inverter welder. According to the frequency of work, can be divided into several grades: 10kHz-, 50kHz, 50kHz-100kHz, 100kHz ~ 500kHz, 500kHz ~ 1MHz, 1MHz or more.

Q: You are given a material which produces no initial magnetic field when in free space. When it is placed in a region of uniform magnetic field, the material produces an additional internal magnetic field parallel to the original field. However, this induced magnetic field disappears when the external field is removed.What type of magnetism does this material exhibit? diamagnetism paramagnetism ferromagnetism Part BOnce again, you are given an unknown material that initially generates no magnetic field. When this material is placed in a magnetic field, it produces a strong internal magnetic field, parallel to the external magnetic field. This field is found to remain even after the external magnetic field is removed.Your material is which of the following? diamagnetic paramagnetic ferromagnetic Part CWhat type of magnetism is characteristic of most materials? ferromagnetism paramagnetism diamagnetism no magnetism: Yes the newest modern metal detectors have controls that will allow you to pick the type of metal you want to detect. And also how deep you want it to check for that metal. You can set them for iron, gold, silver, copper or lead. You can even tell them what metals to ignore such as aluminum. They are very sophisticated now.

Q: I need to know what is the true effect when you place two opposite magnectic fields togther. I know that they repel but what is the technical process that is happening. Also in my theory when you have two opposite magnectic fields i believe that as you compress or bring them closer to each other the magnetic fields are also compressed. Is this true?: When two opposites come together, the magnetic particles bound off each other and do not combine. The particles want to find an opposite charge to create a neutral particle. Regarding to the other question, the magnetic fields are getting compressed.

Q: For example, if you were to put a magnet on either side of the material, the magnets wouldn‘t try to pull together.: Try Copper or Aluminum. They both are diamagnetic, used for 'shielding' in electronic circuits

Q: how is information stored on hard disk . i wanna know it from electronic level?: No. I don't. I have had bad wiper blades often enough to appreciate them. :)

Q: how does electricity or magnet make iron / steel magnetic?: Iron and steel are both 'ferrous' materials . this means that they have particles which can be affected by a magnetic field. The particles tend to align themsleves with the magnetic 'flow' . kind of like leaving a boat tied to shore but in a current. Eventually, the bow will point upstream toward the flow (and the point to which it's tied!), while the stern points downstream. Once the particles get aligned, they tend to stay that way . thereby creating their own 'magnetic' effect. Some materials have more ferrous particles than others, which is why some are easier to magnetize than others! By the way - electrons are not 'magnetic' particles. They are subatomic particles that carry an overall negative electrical charge. Electrons don't get influenced by magnetic fields.

Q: Magnets, barricade, magnetic field: i dont think so i think you can make the field stronger but smaller though. limit the distance but increase the strength. thats just a guess though

Q: I know you can shield objects and electronics/electronic signals wires from interference, but that's electromagnetic. I'm talking about a regular neodynium rare earth magnet. Can it be done with a substance, like lead, as opposed to a powered or electrically induced counterforce?: Yes, there exist many different types of magnetic shields; they work due to their permeability.

Q: i have to do a short answer pleas help! thanks: i think of maximum people who do that are jealous of wholesome romantic relationships through fact (for regardless of reason) they have not been able to looking one for themselves. i think of that their purpose is to make a probably chuffed couple argue or get offended at one yet another, in an attempt to make the instigator experience that their dysfunctional relationships are ordinary. additionally, some anyone is purely a**holes that desire to make certain anyone else depressing.

Q: 1.- how a compass needle moves when it is placed in a magnetic field????2.- why only certain materials are magnetic?3.-how heating a bar magnet would change its magnetic fiel?PLEASEE: The compass needle is rotated so that it becomes parallel with the magnetic field of Earth. This happens because of the magnetic moment of the magnet's atoms, and this way magnet reaches the lowest energy level. The materials have magnetic properties which are determined by the magnetic moment of their atoms, that depends on the atomic mass and hence the shape of the atom. If you imagine (a very simplified model) that each atom contains electrons spinning around the nucleus and around themselves, they form microscopic electric currents microscopic magnetic fields (Electrodynamics explain how is produced a magnetic field from a non-stable current). The field produced by each electron adds up, as each atom's field has the same direction, and we have a magnetic material. The atoms in a magnet have fixed positions, that are determined by the lowest internal energy of the material. If the magnet is heated, it's atoms gain extra energy and start moving faster and more freely. In this way the initial structure is destroyed, and when the material is cooled again its magnetic field can be found different or completely destroyed.
