Q:Why cant magnetic field lines cross?
here is the answer Magnetic field lines are just a representation of the field itself. The lines are not real in that sense, but they tell us where the field is pointing at any chosen point in space. Now if the lines cross, that would mean that the field at the crossing point is pointing in two directions which would be contradicting our original idea. A horse shoe magnet is made of hard magnetic material where the magnetisation is stiff and less flexible than in a soft iron magnet. Hence we do not use a horseshoe magnet for electromagnets because we cannot control the magnetisation as well as we can for the soft iron. However, you can still use electromagnetic methods to magnetise the horseshoe magnet. Nobody knows how earth's field comes about. here is my other answer Field lines don't cross because a magnetic object placed at a point in the field moves only in 1 direction due to attraction or repulsion. If 2 lines crossed, it means the object can move in 2 directions, which is not the case!
Q:Who knows about the rare earth magnetic material? I'd like to know something about it
Rare earth permanent magnet material is a permanent magnetic material made of rare earth metal and transition metal. Rare earth permanent magnet materials have been widely used in mechanical, electronic, instrument and medical fields.
Q:Cheap or free materials for making a magnetic post board?
I was expecting, Oleg, Igor, Boris, Lev and Olga from Moscow.
Q:Does VCD disk use magnetic material and how to record information?
Disposable recording CD-R disc (MPC) mainly used organic dyes, when the CD in the burn, the laser will on a substrate coated with organic dyes, direct burn, burn a "pit", which is "the pit" and not "pit" state form "signal 0'and 1'," this one "pit" can not reply, when firing "pit", will be permanently maintain the status quo, this also means that the disc cannot erase duplication. This series of "0" and "1" information form the binary code, which indicates the specific data.
Q:all atoms have moving electric charges. Why, then. arent all materials magnetic?
because not all materials are made of ionic bonds. which tends to loose electrons referring to the periodical table you will realize that elements from the left to right tend to lose electrons to be stable. the noble gases are stable and doesn't easily form bonds because their out most shells are filled (valency electrons) on like the alkaline earth metals. therefore the magneticy of a substance or materials depend on the elements its made of! hope that helped!
Q:Thickness gages measurement quirks?
I've used ultrasonic testing, not eddy current or magnetic induction. However, no one has answered so I'll take a stab at it. I expect two issues: magnetism and calibration. Materials that are strongly magnetic are called ferromagnetic, while those that don't are called non-magnetic. Stainless can be either ferromagnetic or not, depending on the crystaline structure, i.e. type of stainless and (sometimes) heat treat condition. Could it be that the magnetic properties of the underlying material affects the readings? More specifically, do both methods work with both magnetic and non-magnetic materials. Second issue is calibration. If you calibrate for steel, maybe calibration not valid for stainless, or vice versa. Round or flat should not make much difference. Good luck!
Q:What are the requirements for magnetic materials used in high frequency to reduce what?
The elevation of f or Bm increases, the loss will be greatly increased, resulting in the magnetic material of severe fever, which requires the resistivity of the magnetic material P to be big, in order to effectively suppress eddy current loss.
Q:What material can isolate against warmth, but lets magnetism pass?
What ive understand is ur using a coil, wound like a solenoid. using a frequency generator, u are trying to see the effect that different frequencies have on the plant which is placed some centimeters away So the additional details u want to include something like to reduce effect of heat on the plant blablabla If thats what u are trying to mean.then I'd suggest that u say Use lower power when generating the frequency.(either using lower voltage or increasing coil turns- higher resistance PV^2/R) when u use lower power there is less heat dissipation now if u still want to persist with the idea of using thermal insulators use thin sheet of aluminum where the inner wall of the aluminum is lagged to prevent heat loss by conduction (solenoidaluminum) use thin sheet of aluminum because it reduces transmission of heat via radiation. and Aluminum allows magnetic field to pass through (it does not create a flux between the coil and aluminium) Hope this will help u ;)
Q:magnetism cant pass through magnetic materials because?
It sticks to the magnet. The magnetic material absorbs the magnetism. That's how they make magnets.
Q:What materials block a magnetic field?
Nothing blocks magnetic fields. You can put ferromagnetic materials (like mu metal) to divert magnetic fields around a space, but the magnetic fields are just constrained to lie mostly within the metal, the field strength is increased, and there is still some field present outside it (on both sides). Any metal can that magnets are attracted to, will provide some shielding (as I describe above). Your test using two magnets doesn't do what you thought.
