Q: I was on some sites yesterday, trying to learn more about magnetism when I came over ferroliquids. The person had pictures and said that it felt like oil when touched, but was diffrent for it was magnetic [obviously] and spiked up when interacting with a magnet. More or less the neodymium-iron-boron magnets. So why shouldn‘t oil be like a ferroliquid? I‘d like to know.: A candle is an amorphous solid. Not all amorphous solids are candles. Glass is an amorphous solid. Not all amorphous solids are glass.

Q: CD-ROM recording information principle, specific points, why not use magnetic material?: In digital quantities, there are only 1 and 0 two digits. The computer chips read these 1 and 0 and decode them to make up the sounds, images, or other information we need.

Q: 1. What type of envirnoment makes magnets work best?2. What is an electromagnetic field?3. What is a magnetic field?4. What types of magnets are strongest?5. How have magnets changed over the years?: magnet works best in a low temperature envronment free from any magnetic material. an electromagnetic field is one in which the elecric and magnetic components are perpendicular to one another. the modified space around a magnet is called magnetic field. electromagnets are strongest by the years the conventional magnets have been replaced by more powerful electro magnets

Q: 32. STATEMENT-1 The sensitivity of a moving coil galvanometer is increased by placing a suitable magnetic material as a core inside the coil. and STATEMENT-2 Soft iron has a high magnetic permeability and cannot be easily magnetized or demagnetized. (A) STATEMENTI is True, STATEMENT-2 is True; STATEMENT-2 is a correct explanation for STATEMENT-1 (B) STATEMENT-1 is True, STATEMENT-2 is True; STATEMENT-2 is NOT a correct explanation for STATEMENT-1 (C) STATEMENT-1 is True, STATEMENT-2 is False (D) STATEMENT-1 is False, STATEMENT-2 is True: The answer is C, but that doesn't help you. How will you know if I am right? For example, placing a magnetic material in the coil of a galvanometer could cause it to respond more slowly due to the inertia of the mass, so Statement 1 may not be true. As for Statement 2, iron has high permeability but that means it CAN be magnetized and demagnetized easly, .I think. Rather than just putting your homework questions on Yahoo! Answers and expecting others to give you correct answers, which is really a lame game, it would be better to explain your own understanding of the problem. No one really wants to do your homework for you, and if they say A, B, C, or D, you could do just as well yourself by making a random guess. Instead, ask what it is that you don't get about the question. Then maybe you can actually learn something, OK? I'm not sure at all about my answer, but by explaining it I give others the opportunity to correct my thinking.

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?: I realize some people write like they are texting, but its annoying. Know, not no. cat back not cut back I have a, not I got a what is the question? but just need to about the cut back

Q: Magnetic flux density, B, and magnetic field strength, H, may experience changes at the interface of materials whose magnetic properties differ from one another. Consider the following:i. magnitude of Bii. normal component of Biii. tangential component of Biv. magnitude of Hv. normal component of Hvi. tangential component of HWhat combination represents the properties of an electromagnetic wave that are continuous (i.e, do not change) across such an interface?a) i and iib) ii and vic) iii and vd) iv and vi: It looks like most people are saying tire but they are wrong it is by the door sticker . What is on the tire is maximum pressure and weight the tire can safely carry, so unless you have your vehicle loaded to the max, you do not need to put in what the tire says. the only exception to this was when Ford put on firestones on their Explorers and had to low of pressure on the door.

Q: Explain why an iron bar can become magnetic but a wooden pencil is not magnetic.If you could relate this to physics, that would be very much appreciated.: because pencils are yellow and due to the fact people hate gingers you can use the transitive property to assume the pencil has no soul and therefore can not be as cool as iron

Q: Hello.We‘re measuring the thickness of an organic coating on carbon steel and we have two probes: one works by magnetic induction, one by the eddy current method. They‘re both right-angle probes designed to measure the inner coating of pipes.When testing on a flat sheet of stainless steel, both probes give accurate measurements. But when tested on a carbon steel cylindrical pipe, the eddy current probe is way off (reading 667 um when put right against the metal)!We will be using the ‘proper‘ probe, but still I‘d like to know how the eddy current probe behaved in such a way. Is it because of the geometry (flat sheet vs. pipe)? I suppose eddy currents would take different paths.I‘m not an engineer as you will have guessed.Also, I know NF/FE means ferrous metals and NC/NF means nonferrous, but what do these acronyms mean exactly?: 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: if you know a good site to find the information please include it.: yes you can straighten it.you will need a vice and if you have a torch it would make it alot easier.take the axle off putt it in a vice and beat it straight with a heavy hammer or sledge be carefull not to mess up the threads or lose your bearings or cotter pins when you remove it.the trick to it is to put the axle in the vice right up to the bend leave the bend on the top beat it straight then role on flat surface and correct as needed

Q: electric field applied to material controls magnetic properties,Rutgers university: The magnetoelectric (ME) effect is the phenomenon of inducing magnetic (electric) polarization by applying an external electric (magnetic) field.
