Q:i just wanted to know: I've read the other answers and I'm surprised that no one has gotten the right answer yet. There is type of metal that is found naturally in the earth and is already magnetic in nature. It's what the original compasses were built with. In ancient times, it was called lodestone. I believe in modern times it's call ferrite. Iron and steel (which is iron with oxygen) can have their atoms aligned to become magnets but only after being exposed to a pre-existing magnetic field. There is no substance including iron, steel or lodestone that can produce electricity of it's own accord, except for static electricity. In order to do so, they would have to be placed along with wires and such to create a circuit. Electrons and the electromagnetic force won't flow without creating a circuit to flow through, again, except for static electricity. Ed

Q:ok this has been bugging me for a while now. if supposedly venus, earth, and mars had/have a molten core then why is earth the only one with a magnetic field. does it have something to do with plate tectonics and the moon.: Actually, Venus is the only one WITHOUT a magnetic field. Mars may have a magnetic field. But Earth, Mercury, Jupiter, Saturn, Uranus and Neptune all have magnetic fields. *below is copied and pasted from source link Scientists believe, although it is not certain, there are two essential ingredients for generating a magnetic field. Those two ingredients are magnetic material currents A bar of iron can be made into a magnet by wrapping it with wires and running a current through the wires. It is believed that a planet, or a star, can generate a magnetic field if it has both of the two ingredients above. It must have enough magnetic material, and it must have currents moving inside the magnetic material. If a planet does not have enough of either of these two ingredients, it will not have a magnetic field. Planets which do not have magnetic fields include Venus (moves very slowly), and Mars (most the iron is on the surface, and not molten).

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:What is the sign of the magnetic anomaly of an igneous rock at the equator during normal geomagnetic polarity? Does the sign of the anomaly depend on the latitude? Why?: Magnetic anomaly are strips of magnetic material on the earth crust and in the ocean floor. Magnetic anomaly doesn't really have an average magnetic component because it's always changing. Magnetic anomaly is found at lower latitude where ventilation is exposed. Volcanoes and at ocean ridges where volcanic activity is located is where magnetic anomalies where be located.

Q:A. Liquid iron B. Metallic hydrogen C. Molecular hydrogen D. Water-ammonia slush I think A and D may be responsible, but i‘m not sure whether B and C are.: I think it's D, that's what I was able to discern from this website.

Q:What is Developer Mix?: In present day laser printers we use mono component toner. The ink or the toner is magnetic material so its sticking to the magnetic roller in the toner module. Earlier days and present day high volume printers do not use magnetic ink. There we use two different materials or dual component development. The toner is carbon particle and non-magnetic. The developer is ferrous material it sticks to the magnetic roller and the carbon powder sticks to the developer due to electrostatic charge. This developer is used only as carrier and never exhausted. This developer and toner mix is called developer mix.

Q:what is the capacity of MAGNETIC Field required from a set generator to produce 6000 watts?: As long as you know what you are doing, you pay close attention to your surroundings, and you dress appropriately you should be very safe. Take a class if you can that will help prepare you and drive in low traffic areas to better prepare yourself. Also remember that most motorists aren't looking for motorcycles. Motorcycles riding is a blast and very exhilarating, but just like everything else there is great responsibility. Prepare yourself and you will be fine.

Q:Must the magnet be magnetic?: The magnetic material is not necessarily magnetic. The magnets magnetic material and soft magnetic material, if magnetic material has magnetism, if only the magnetic field of soft magnetic materials exist or that only to be magnetized when are magnetic.
