- Q: what makes a magnet on the atomic level?
- Magnetic materials have electrons which can be influenced to all travel clockwise or counterclockwise around their atoms. Electrons are electrically charged particles, and they generate magnetic fields as they move. If they all move in the same direction, the individual magnetic fields combine and the overall field increases in strength. Non-magnetic materials have as many electrons in clockwise as counterclockwise orbits, and this cancels any overall magnetic field. Magnetic materials are magnetized by exposing them to an external magnetic field. This aligns all the electron orbits, sort of like a comb moving through hair. Heating a magnet decreases its magnetic strength. Atomic vibrations increase and these disrupt the symmetry of the electron's orbits. It is sort of like the wind blowing hair around after it's been combed.
- Q: The magnetism of a permanent magnet results from __________.a) interactions with Earth‘s magnetic fieldb) the magnetic moments of nuclei in the material making up the magnetc) electric currents inside the magnetd) the magnetic moments of electrons in the material making up the magnet
- The option,d) the magnetic moments of electrons in the material making up the magnet is most appropriate but to some extent, c) electric currents inside the magnet also contributes. The options, a) and b) do not contribute to permanent magnetism of materials.
- Q: The magnetic material can attract electromagnetic wave? The magnet can attract magnetic materials? What meaning, thorough point,
- This is the so-called "Kerr effect"; CD data read computer is the application of the Kerr effect. The range of magnetic materials is very broad, based on its magnetic properties can be divided into: magnetic material, soft magnetic materials, magnetic materials, spin diluted magnetic materials. According to use also can be divided into the guide magnet material for permanent magnet material the information storage materials, such as magnetic core. So far, the magnetic material or human cognition of primary level, but mankind has realized the magnetic human cognition is dark matter, black holes, or unknown key.
- Q: What is the Curie temperature?
- For all of the magnetic material, and not at all temperatures are magnetic. Generally, the magnetic material has a critical temperature Tc, the temperature above, due to the severe high temperature thermal motion of atoms, atomic magnetic moment arrangement was disordered. Under this temperature, the atomic magnetic moment order, spontaneous magnetized objects become ferromagnetic.
- Q: What kind of magnetic material is difficult to demagnetization at high temperature?
- From the normal temperature to high temperature, magnetic material will be reduced to subside, a ferromagnetic paramagnetic temperature change is called the Curie temperature.
- 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
- it cannot be done. If it could it would have been used to build a perpetuum mobile motor and this just breaks the laws of thermodinamics
- Q: why does a material with randomly aligned magnetic domains fail to exhibit magnetic properties?
- If you sell them they are great MONEY. Check your warranty It may not be valid if you use them
- Q: What is meant by changing Magnetization by Neel rotationNot geometric rotation?Neel Rotation?
- The magnetic fluids are colloidal suspensions of magnetic nanoparticles dispersed in a carrier liquid. The nanoparticles are magnetic monodomains and usually have irregular shape. The direction of the magnetic moment relative to the particle is given by the interaction with the easy magnetization axis which can have a crystallographic nature in the case of hard magnetic materials or a morphological nature in the case of soft magnetic materials [1] when the magnetic moment is coupled with the shape anisotropy axis of the particle. The strength of the coupling increases with the ellipticity and volume of the particle and is proportional with the squared cosine of the angle between the magnetic moment and the anisotropy axis [1]. Although free to rotate relative to the particle (Néel rotation), the rotation of the magnetic moment under the action of an external magnetic field induces a rotation of the particle bulk (Brown rotation) and the particles tend to align with their anisotropy axis parallel to the field, thus resulting in a macroscopic anisotropy of the magnetic fluid. This macroscopic anisotropy is the main cause of optical anisotropy of magnetic fluids: dichroism and birefringence.
- Q: why does the magnetic force go through aluminum foil?
- well, i can tell you that a friend of mine and i got a 1995 ford escort to catch air. it was a very hard landing though.
- Q: i have to do a short answer pleas help! thanks
- Basalt from volcanic activity in the ocean floor (which is full of iron, thereby creating the mineral Magnetite cause localized disturbances of the ocean basins. Since Ferrous materials carry the magnetic fields much more effective than non-ferrous elements, magnetic fields are concentrated around these iron-rich deposits. This is a very important effect for submarine vessels (for navigating) and for surface combatant and non-combatant ships that transit underwater mine fields. Since most mines are magnetic in nature (they arm and release when they detect a deviation in the magnetic fields around them), a ship passing above that wishes to not be destroyed much produce its' own magnetically neutral field to the local field of the Earth, which changes greatly based on where it is in the world. This neutrality is achieved by knowing what the deposits' magnetic fields are in the ocean floor and thereby emitting a polar-opposite force on the hull of the ship to make it look (to the mine) that there is nothing above it.
