Q: What are the advantages of magnetic materials in RAM?: When the frequency increases, the magnetic conductivity of the material will be reduced, and the magnetic properties of the magnetic material are influenced by many factors. Generally, the permeability and saturation magnetic induction of metallic magnetic materials decrease with the increase of temperature.

Q: 1:5 SmCo magnetic materials, what is the exchange rate of 2:17 SmCo magnetic materials materials: From the application function, the magnetic material is divided into: soft magnetic material, permanent magnetic material, magnetic recording - moment magnetic material, spin magnetic material and so on. Soft magnetic materials, magnetic materials, magnetic recording materials in magnetic moment both metal material and ferrite material; and the rotating magnetic material and high-frequency soft magnetic materials is ferrite material, because the metal will produce large eddy current effect in high frequency and microwave frequency, resulting in metal magnetic material can not be used, and the resistivity of ferrite is very high, will effectively overcome this problem, widely used.

Q: What are ferromagnetic materials?: The characteristics of soft magnetic materials is the relative permeability of Ur and saturation magnetic induction of Bmax are generally relatively large, but the coercivity of Hc than hard matter much smaller, surrounded by the hysteresis loop area is very small, the hysteresis is not significant, the soft magnetic material is easy to be magnetized in a magnetic field, but because of its coercive force is very small, so it is easily to magnetism, therefore, the soft magnetic material is another reason why it is suitable for the manufacture of iron core electromagnet, transformer, AC motor, alternator and other electrical appliances in the.

Q: I‘m doing a small experiment with my son for a science project and we are looking for magnetic resistance in typical household objects. So far we have found nothing. Glass. plastic, paper, water, nonferrous metals, wood, you name it. Of course it depends on the thickness of the material and the strength of the magnet. We are working with small neodymium magnets.: There exist several nickle-iron (plus some other impurities, like molybdene) alloys that can do that: mu-metal, permalloy, supermalloy, nilomag, sanbold. Mu-metal is often used for shielding of magnetic fields in household appliances.

Q: Why can't capacitors use magnetic materials?: There is only an electric field in the capacitor and there is no magnetic field. Is the magnetic material indifferent? As long as you wish, you can still use the iron sheet to make the capacitor.

Q: why does an iron core increase the magnetic induction of a coil of wire?: this is because it intensifies the magnetic field since by putting it close to a magnet, it itself becomes a magnet thus making the change in magnetic flux greater thus an increase in the magnetic induction of a coil of wire

Q: I know some effects would be the likely seeing of thee Aurora lights almost anywhere on Earth and because of more radiation sun cream would be a definite part of every day life but would be still be able to walk down the street, I am sure we can as our Magnetic Field Shields us from most of the radiation?Thanks.: the interior the earth has liquid iron that strikes in convection currents to hunt for thermal equilibrium. the warmth that melts the iron is being generated via a mix of radioactive factors interior the interior and gravity compressing the interior. The shifting iron generates a magnetic field. because of the fact the warmth is sent to the mantle and the radioactive factors provide up the decay technique, much less warmth is produced and finally the iron will solidify. whilst that occurs the earth's magnetic field will weaken billions of years into our destiny. yet we even have short term weakening. As Raymond documented, there are additionally short term reversals of the magnetic field. that's not properly understood what the mechanism for that's. even if that's for sure been happening for an prolonged time as documented via the magnetic field reversals frozen interior the forged lava flows alongside the mid-Atlantic Ocean ridge.

Q: What material blocks magnetic lines of force?: The only thing that will completely do it is a superconductor below its critical temperature exhibiting the Meisner effect.

Q: why does the rock of the ocean floor have a pattern of magnetic stripes i reallly need help thnks: Because the rock, which contains ferrous material extrudes slowly over millions of years. Through this period of time the Earth's magnetic field reverses occasionally, this makes the rock form to match the magnetic direction of the time. Because the floor is produced so slowly, it's stripes represent the polarisation of the time at which each piece is formed.

Q: Is this something that can actually be developed? Where did the idea of some kind of electric or magnetic or whatever shield come from? With a deadly layer of high speed space debris accumulating around our Earth right now, I wonder if we‘ll ever be able to get off of the planet without developing this shield technology.Is shield technology something that can theoretically be developed? And if so where can I read about the theories behind it?Thanks: Mark, The best resource you are looking for is well. not yet written. The shield that you see in space show is, as of today, fictional. It can absolutely not exist. At least none that can be applied to any general particle in space or on earth. It may be possible for magnetic materials. How? well, assume this shield was created of layers' of magnetic 'sheets' with each sheet having opposite polarities. Now when some unmagnetized object (say an iron bullet), but which is made of magnetic material, enters the first sheet, it is induced with a polarity opposite to that of the first sheet's magnetic direction (let's just assume it is north). But when it reaches the next sheet, it would be repelled, because the sheet would be north, and north magnetic field would repel the north facing bullet. This is in theory, possible. if you had a strong magnetic field. The same can be applied for electrically charged particles. say protons, electrons. But for a neutral, nonmagnetic atom (which is what most of the world is made up of) there is no known way of creating a 'force field'. The reason lies deep in quantum mechanics, and the constraints on the energy of a particle in a potential field. These are just my thoughts, they don't necessarily have to be right, but it should give you something to think about.
