Q:what does it mean to have a permiability less than one or more than one, i know less than one is diamagnetic and more than one is paramagnetic, but why the value 1? and whats with the negative value of permiabilities?one more thing, if water is diamagnetic that means it bends the magnetic fields around it, does this mean if i submerge a nyodenium magnet in water, no metal will be attracted to it under water? (since the magnetic field has no where to expand to, unless they expand in between the molecules): Genius' gave a comprehensive answer; yet I' d like to add. B is called the flux density, which is number of lines per unit cross-section in a plane perpendicular to flux lines. With μ 1, B is more than that outside the material experiencing the field H. In case of water (μ 1) flux lines get very much spaced out so that B is actually less than what prevails in the field around. A Ferro-magnet in water has flux lines spaced out wide in comparison to air for example. If another piece of Ferromagnet is brought near it would move fast towards the main magnet with much more alacrity, I would imagine. It brings in the concept of 'magnetisation' and its imtensity(M) that is the magnetic moment per unit volume, since attracting and repelling magnetic 'pole pair' develop a moment. B/H 1 + 4(pi) M/H. μ 1 + 4(pi) X where X is called magnetic susceptibility. The equation could be written without H in denominator though, it is to show the dependence of μ on H also. In SI units '4(pi)' term vanishes. For water values of X are at its freezing (melting) point : -0.7019 (solid state) -0.7177 (liquid) -0.7199 (liquid) 20deg C.

Q:I am unsure as to whether or not the metal that moves within said field must be ferromagnetic.: It needn't be ferromagnetic. The changing magnetic field will produce an electrical current in the copper. Feromagnetism is the metal being brought near the magnetic field taking on a strong magnetic field.

Q:Our science textbook says it is, but then a scientist friend said it wasn‘t.: Nickel is ferromagnetic. Usually, that means magnetic. It isn't a particularly strong ferromagnet compared to iron or cobalt, which may be what your friend means. The other ferromagnetic elements are dysprosim and gadolinium, neither of which are common and both have Curie temperatures below room temperature, so they're kind of useless in most cases as magnetic materials.

Q:Is the hard drive in a computer likely shielded by a metal casing? Why or why not?This is dealing with protecting it from magnets.: The platters are made from a non-magnetic material, usually aluminum alloy or glass, and are coated with a thin layer of magnetic material. Older disks used iron oxide as the magnetic material, but current disks use a cobalt-based alloy and non-magnetic.

Q:It would also be nice to explain this in terms of inductance, permeability, and permittivity within SRR metamaterialsI‘m currently an undergraduate participating in research for the summer. I‘ve only taken general physics 1 and 2, but please dont hesitate to give details that might be too advanced for me to understand. I plan on reading more about any details that I don‘t understand or have not learned yet.Thank you very much: stop being a tattle tail teach him or her how do it your self let him no and tell him what happens if he doesnt do it right

Q:what makes store buzzers go off? do the bar codes make them go off as well as the magnetic things?: I think most of them work on the principle of induction. There's a litte coil or loop of metal in most of the tags, and when this passes through the barriers at the door, it sets off the alarm.

Q:How can a strong magnet be drawn apart?: When powerful magnets are pulled together, they can be separated only with great force, so they should always be very careful when they are separated, because the magnet itself will stick together, and it may pinch fingers. When magnets are attracted to each other, they may also damage the magnet itself by hitting it (hitting the corner or hitting a crack).

Q:A microscopic magnetic region composed of a group of atoms whose magnetic fields are aligned in a common direction is called a(n) ____. In most materials, when these groups are randomly distributed, the substance will show ____ magnetism. domain; no pole; some cell; unusual ion; strong: It is called a domain and randomly distributed domains show no magnetism

Q:I have two magnets. What can I put between the magnets, so that they will not repel or attract as long as it is between the magnets?: Seeing as it says on the side of the tire, what the maximum limit is.not sure what you need help with. You already have the answer available.

Q:what materials can shunt magnetic fields other than iron?: Short answer, yes. It is all about the magnetic properties of the materials. pedia has a good explanation of ferro-magnetism, para-magnetism, etc.
