- Q: What metals are not attracted by magnets, please?
- Experiments show that any substance can be magnetized more or less in an external magnetic field, but only in varying degrees of magnetization. According to the characteristics of a substance in an external magnetic field, substances can be roughly divided into three classes: paramagnetic, diamagnetic, ferromagnetic.
- Q: How can permanent magnets be magnetized?
- It should be said that there is no element attenuation, only demagnetization is not net, and the latter magnetization direction is opposite, forming polarity reduction, so performance magnetization effect is not good.
- Q: I‘ve built a sensor that measures current through a wire by measuring the magnetic field, but magnetic fields from other wires are making big noise signal. Is there any way I can protect the sensor?
- Earth’s Magnetic Field There is much uncertainty about the origin and nature of the earth’s magnetic field. A simplistic model is that of a giant bar magnet with a dipole field surrounding it (Figure 14 – 1). Measurements made of the orientation and strength of the magnetic field in thousands of locations around the earth suggest the bar magnet model, which is roughly spherical and has lines of force plunging into the polar regions, is a good approximation of the real magnetic field. The earth’s core is thought to be largely made up of molten iron, which might be the source of the field. Siesmic studies indicate that the inner core is solid and the outer core is liquid. The inner core is above the Curie temperature, so it cannot contribute to the Earth’s magnetic field. Modern theories suggest the magnetic field is caused by flow of material in the outer core which generates a flow of electrical current, which probably also contributes to the formation of an electromagnetic field.
- Q: what material(s) can magnets not penetrate?
- wood plastic lead granite
- Q: Should the iron core of the electromagnet be made of hard or soft magnetic material? Why?
- Because the core in the work, will collide, longer, more on the core of the electromagnet core. If you wear stress is relatively small, there is no requirement on what power, can use soft magnetic materials. In my humble opinion, please be careful.
- Q: if i made a sleeve for an external hard drive, what could i make it out of that would block magnetic waves? (even if i dropped an industrial strength magnet on to it by mistake)
- Distance is the only protection. the magnetic force follows the inverse square law. The strength of the force is weaker the further from the source you get. Nothing stops it, and the only thing that might effect it is a magnetic material (iron, nickel) which would itself become a magnet in the presence of these forces. You can only keep things away from magnets, you can't sheild them. Dont confuse them with electromagnetic force, which can be redirected trough sheilding. very different things.
- Q: I am an inventor, the invention Im currently working on requires magnetic pushing power only. I need to stop the pulling force on the sides and back. So im trying to have the pushing side exposed only. What can i use that‘s readily available.Thanks john
- I don't know about blocking the magnetic pulling force, but maybe you could find a way to use the gravitational force to move an object horizontally by developing a material that thinks it is always falling, or moving downhill due to the vertical gravitational force, even though it isnt, like a dyslexic steel plate that doesn't know up from down.
- Q: The magnetic material that is often used as a permanent magnet is
- These are the main market of permanent magnetic materials, and some from the original production process or cost reasons, can not be applied widely and eliminated, such as Cu-Ni-Fe (Tong Nietie), Fe-Co-Mo (Tie Gumu), Fe-Co-V (FeCoV), MnBi (Mn BI)
- Q: when one refrigerator magnet is placed upon the other then they either slide easily or somewhat there is disturbance when they slide. BUt when the magnet on the top is rotated in 90 degree sidewise then when we again slide it, there is exactly opposite to what has happened before. If they slided easily before now they slide with some difficulty and vice versa.Why does this happen?explain the orientation of magnetic field or magnetic poles
- Truth be told it is hard to determine. There is no such thing as a clear line between what defines an orientation, preference, fetish, etc. They all fall on scales that vary wildly and each is formed by an amalgamation of our genetics, our environment, and our own choices. Some people might find a particular fetish as difficult to alter as their gender preference others might find that they change what they like on a weekly basis. I have even met bisexuals who at one point cannot stand the thought of one gender and the next day switch altogether. It's just phrasing and it doesn't really mean anything anyway. If you are talking about what to say in colloquial language then I would say that neither word indicates any kind of permanence more than the other. Honestly I just wouldn't let it bother you.
- Q: what do the following mean?1.dipole moment 2.magnetisation
- The origin comes from the influence of earths magnetic field. When a material is formed it lines up with the earths magnetic field and creates its own magnetic field parallel to how the earths magnetic field is flowing in that particular area.
