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 causes the positive and negative forces on a magnet and the earth poles?
The core and mantel of the earth is primarily made of metal. The temperatures are so great that the metal is melted (except, supposedly, in the inner core, where the density of the metal makes it a solid). This melted metal flows around in the core, and through its movement creates the magnetic field. [A magnetic field is just an eletric field that is moving. In a melted metal, the electrons are able to move around more freely, causing the electric field. The motion of the liquid metal creates the magnetic field.]
Q: becoz am trying to rotate the shaft of a generator using magnetic force
If you mean you are trying to drive a generator using only magnets, you are going to be disappointed. Despite all the claims advertising free power, usually with a load of pseudoscientific evidence, it is still contrary to the Laws of Thermodynamics. You cannot create energy from nothing.
Q: magnetic susceptibilitybtw magnetic susceptibility - the degree of magnetization of a material in response to an applied magnetic field. ()
Hi, It’s an interval variable because the difference between two values is meaningful. As you probably know, a ratio variable has all the properties of an interval variable, but it has a definite 0.0 point. Magnetic susceptability is usually measured by seeing whether an induced current increases or decreases with the material serving as the magnetic core. Since magnetic susceptibility can be negative as well as positive, I suppose that, in theory, there must be some point at which the susceptibility is 0.0. So, in that sense it’s probably a ratio variable as well as an interval variable. I frankly think you’d be much better to post this in the physics forum. Although I’m an electrical engineer, I’ve been teaching college math for too long to remember all of that stuff about susceptibility. Sorry. formeng
Q: what are the characteristics of a material having high coercive force?
The coercive force which relates to the coercivity of a magnetic material ( i.e. ferromagnetic) is the reverse magnetic force in terms of the magnetic field strength H that will reduce the magnetic flux density B in the material to zero. A material with a high coercivity will have a broad hysteresis curve.
Q: I know that the information (bits) are encoded onto and read from a hard drive disc by a magnetic writer/reader in tracks and sectors however I am not sure how the magnetic material on the platter is separated into magnetic domains representing the bits instead of just spreading the magnetism over the entire track like it would on an analog tape. Also, are sectors physically separated or just separated by saying this sector begins and ends here and that one there If you could answer these questions I would greatly appreciate it. Thanks
this sector begins and ends here and that one there ^ this.
Q: Which is a stronger magnetic material:Iron or steel?**PLZ ANSWER** !THANK YOU!
IronTry it out by stickin a magnet to iron and steelu will find iron attracts wid a higher force :)
Q: For inductive loops at traffic lights to detect cars, must the cars conduct electricity or a magnetic field?
The car must have at least some parts that can be magnetized, like iron or steel. I doubt if an all Aluminum car would be detectable. Certainly an all plastic car would not be detectable. I'm not sure how much magnetic material a car has to have for the road inductor to sense it. Probably all that's needed is a steel motor block. Some of these all electric cars might not have enough steel to be detected. Basically its like sticking an iron bar inside, or near, a coil. The inductance changes dramatically because the the magnetic field of the coil induces a magnetic field in the bar which adds to the coils field , and that can be measured.
Q: Can a container with its interior covered with magnetic material be used to cancel out weight?
Maybe, but not generally.
Q: I have really strong magnets, what materials can I use to block or shield magnetic fields?
Other magnets with opposite polarity.
