- Q: What is Curie temperature? What is the working temperature of a magnet?
- The ferromagnetic material is magnetized with strong magnetism, but with the increase of temperature, the thermal motion of metal lattice intensifies will affect the ordered domain moment, when the temperature reaches the neat enough to break the domain magnetic moment, magnetic domain disintegrated, the average magnetic moment becomes zero, the ferromagnetic material magnetic disappear into CIS magnetic material, a series of ferromagnetic properties associated with magnetic domains (such as high permeability, hysteresis loop, magnetostrictive etc.) disappeared. The permeability of the ferromagnetic material of the corresponding permeability into paramagnetic substance. The temperature corresponding to the disappearance of ferromagnetism is the Curie point temperature.
- Q: What metals are not attracted by magnets, please?
- We call paramagnetic and diamagnetic substances weak magnetic substances, and ferromagnetic substances are called ferromagnetic substances. Generally referred to as magnetic material is a strong magnetic material. Magnetic materials are difficult to be divided into soft magnetic materials and hard magnetic materials after magnetization. It is easy to remove the magnetic material after magnetization. It is called soft magnetic material. The material which is not easy to touch is called hard magnetic material. Generally speaking, soft magnetic materials have less remanent magnetism, and hard magnetic materials have larger remanence.
- Q: Okay, well I‘m doing this science experiment. My variables are the two types of magnets. One is just a regular magnet and the other is a neodymium magnet. So I lay down the dollar bill and first see if the regular magnet works (it won‘t). Then I take the neodymium magnet and see if it attracts the dollar (it will). But I have no idea what I could measure on this experiment. Maybe how far the dollar bill lifts off the table? But I really probably need something else. Any help, please?
- Paper money contains no magnetic materials. Magnets will not attract it, unless you got some candy slime stuck to the magnet.
- Q: is there any kind of magnetic shielding that is not made from materials that are themselves attracted to magnetic fields
- No. blankets help people because we generate heat and it keeps the heat from escaping Batteries emit no heat
- Q: why does a material with randomly aligned magnetic domains fail to exhibit magnetic properties?
- No car manufacturer recommends using them and some even recommend specifically they not be used. Since these are the folks who design and build your engine I would trust them, not the guy looking to make a buck off your guilt by claiming you need to use their product to take care of your car properly.
- Q: hey i have always wondered what a magnetic field is??? i mean i know a electric field is electrons and this give a electrical charge and photons are the particles of light(which is also a wave) and that is called electromagnetic radiation. but what is a magnetic field, i know it is created by electrons moving and when thier all in one direction, you have a magnet, but what is the field, is it composed of photons(wave), just like how a electric field is electrons, are the electric and magnetic fields the same thing but just in differnt forms or is it some other particle or wave or both (electrons are also waves) . i am really confused as to what it is, i have checked google and they really dont tell you, do we not exactly. well any info would be great. thx
- Electric fields and magnetic fields are properties ,which space with material or vacuum acquires, which can affect the electric charges or magnetic dipoles. The cause for these may be charges and/or their motion. But once they exist we need not bother about their origin, we can still predict what will happen to electric charges or magnetic dipoles in their presence. When there are some how oscillating fields are created then they have a property by which one type of field can create another type of field. Then the energy flow also takes place. This situation is called electromagnetic field. Such fields are also equivalent to particles called photons which are different from ordinary particles in many ways.
- Q: what is the materials that destroys the magnetic force field?
- its strong and hard so it doesnt get scratched easily
- Q: classifications and devices of magnetic heads?
- If I were you, I'd give it some time and see if there's a way (other than his facebook messages) to prove what he's doing. It's not going to go over well that you were reading his messages, even if it did prove he was doing something behind your back. What I don't understand is why can't you befriend his friend? If y'all hung out together as a group from time to time, it might make you comfortable enough to relieve him from having to choose between being there for his friend and keeping you happy. Just a suggestion. Really, if you trust him, I wouldn't worry about a few rides, even though he didn't tell you about them. It's most likely he didn't tell you because he knew there was nothing for you to be concerned about, but he didn't want to make you mad over it.
- Q: But where is current in the case mentioned above?????
- you are grounded there for the current passes through you
- 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 of-A non-magnetic material-A permanent magnet-An electromagnetRemember that your description of the activities should be about the domains of the magnet and not its polarity.
- Its very easy.you know similar to class environment I.E---give the simple example 1)Before the teacher comes the students are like domains arranged in zig zag manner playing(lattice vibrations) around and making hell out of heaven 2) when the teacher comes(external magnetic field)they slowly allign.one student signals the other(increasing of favorable domain in the expense of others)to turn to teacher at board 3)permanent magnets are like the sincere students in class who never make any plays in class like you 4)electro magnets are like class behaviour of students in teacher's presence
