Q: Magnetostatic theory: I've never heard of men needing a daily dose of iron. Women do, due to obvious blood loss. Perhaps someone told you this, or you read it someplace, but it isn't true. Men do need to maintain Vitamin C and Magnesium and Potassium levels, as well as protein daily, but iron, haven't heard that one. The others I mentioned are lost from sweating from exercise, urine, and other activities, and the protein is especially important for our muscles and brain.

Q: What is the basis for a substance to be magnetized?: The material is composed of molecules, molecules are composed of atoms, atom is composed of atomic nuclei and electrons. In the atom, electronic non-stop rotation, and around the nucleus. These two kinds of motion of electrons will produce magnetic. But in most material, electronic motion direction all the same, out of order, the magnetic effect of offset. Therefore, most of the materials under normal circumstances do not show magnetism.

Q: when we move a magnet towards a coil to which no battery is attached why emf and current are induced in it.what force is actually acting on field lines.pllllllzzzzzzz answer: Electric Current is induced because it is a closed circuit made of a conducting material, Magnetic and Electric Fields are self sustaining in nature, they maybe closely related but the core unification of Magnetic and Electric forces lies deep within modern, or maybe undiscovered Quantum-Relativistic Electrodynamics comprehendible to only a handful of people. We can explain only the magnitude analogue of current, with the help of the principle of 'conservation of energy'

Q: What is the demagnetization temperature of soft magnetic material 430F?: Ferritic stainless steel solid solution, the temperature below 900 DEG C group had no obvious change, the hardness increase with the change of temperature slow; 900 DEG recrystallization, the hardness decreased significantly after heat treatment at 475 DEG C; the precipitates increased, the hardness increases, the corrosion resistance of a serious decline, that there were 475 C brittle the phenomenon of.

Q: You have been given the task of describing the theory of magnetic domains to a class of 5th graders. You have enough large paper arrows to give one to each student. Describe your plan to show them the domain nature ofA non-magnetic materialA permanent magnetAn electromagnet: This sounds fun. You don't even need arrows really. This is how I'd do it: Put all the students (the more the better--like 100 or more would be great) in a clump in an open space--go outside if need be. Tell them to close their eyes and turn in circles until everyone is facing in a random direction. Now tell them that they are like atoms with magnetic dipoles. No arrow required, just say the dipole moment is in the direction they are facing. If they are facing in random directions, their alignment describes a non-magnetic material. Now tell them that in a permanent magnet, a dipole moment tends to line up with it's neighbors. But it costs energy to move, so it doesn't want to move more than necessary. So tell them to rotate as little as possible to line up with (face the same direction as) their neighbors. Move slowly and no talking. If it works out, you should have clumps of students facing a certain way--those clumps are like domains. Finally, in an electromagnet, an extermal field is induced, which is so strong that it compels all the dipoles to allign with it. So on your command, the students should snap to and line up in your chosen direction. If the material is permanently magnetic, the moments (students) will stay aligned even after the field is removed, because of the influence of their neighbors all facing that way. However, if the material is not magnetic, then thermal fluctuations (like fidgetty students that can't stand still) will have the students facing randomly a short time after the external field is removed.

Q: What is the difference between NdFeB and ferrite in magnetic materials?: Ferrite: high resistivity, wide range of work, can be used in high frequency state... But the residual magnetic induction intensity and maximum magnetic energy product are lowNeodymium iron boron: with "magnetic king" said, as the name suggests, the magnetic energy is high, the remaining magnetic induction intensity, maximum energy products are very impressive, coercive force is also high and low points.. But it is easy to oxidize, Curie temperature is low and the working range is not wide.

Q: Just for the convenience of using magnets on a surface, or is it actually practical in some other way to use a magnetic material?: This Site Might Help You. RE: why are refrigerator doors magnetic? Just for the convenience of using magnets on a surface, or is it actually practical in some other way to use a magnetic material?

Q: I know that MuMetal is good for shielding from magnetic shields, but MuMetal is magnetic (in the sense that magnets attract to it).Is there anything similar to aluminum/plastic/silver etc. which can shield from magnetic fields which isn‘t magnetically attracted?: Try CAT back instead of cut back.

Q: what is the materials that destroys the magnetic force field?: Another magnetic force alone can neutralise the magnetic force. Even shorting the north and south pole by an iron rod can also neutralise the magnetic force.

Q: So may book says The direction of any magnetic induction effect is such as to oppose the cause of the effect. I have read many internet fora and posts but I could‘nt understand Lenz‘s law in simple English.And the right hand rule too. Where should I point my thumb or my fingers about to curl? Thanks: Lenz's law means that when you cause a magnetic induction effect in something, the induction effect will push away what is causing the effect. Maybe this is why motors work. The right hand rule is using your right hand, your fingers curl around the object and the thumb poiints up. Make sure you know when to use the right hand and when to use the left hand.
