- Q: moving charges/current creates a magnetic field around the conductor.so why dosent an electron?if it does why arent all objects magnetic?
- It does, and they are to some degree. What happens is that when the electrons get together in an atom, they pair up in such a way as to minimize the magnetic energy - that's (partially) why the atom's orbitals fill up the way they do. If you have an atom with an odd atomic number, you get unpaired electrons in the outermost shell. But these atoms tend either pair up in molecules (H2, N2, etc.) so that these electrons pair up, or form crystals and shed the outermost electrons to what's called the conduction band - the electrons stay in the material but don't stay in orbit around the atoms, making them conductive. All this pairing up makes the magnetic moments cancel out (like placing two magnets together, north-to-south ploes) leaving a non-magnetic material. The electrons themselves also spin on their axis, making them magnetic even when they're not in orbit - again, they pair up in such a way to minimize the magnetic energy. The actual physics behind it can get pretty complicated, but that's it in a nutshell.
- Q: I have a large collection of a magnet brand called supermags and am looking for any material that can redirect a magnets field. I have already tried mumetal and it only stuck onto the magnets. Any advice?
- I do not think any material blocks magnetic force. I know electric current can effect the force, but I don;t think that is what you mean.
- Q: 1:5 SmCo magnetic materials, what is the exchange rate of 2:17 SmCo magnetic materials materials
- The magnetic material is morphologically. It includes powder material, liquid material, block material, film material and so on.Magnetic material is widely used in electroacoustic, telecommunication, electric meter, motor, memory element, microwave component and so on. Magnetic tapes for recording language, music, image information, magnetic storage devices for computers, vouchers for passenger travel, magnetic cards for fare settlement, etc..
- Q: The problem is as follows: There is a point magnetic dipole embedded at the center of a sphere (radius R) of linear magnetic material of permeability μ. What is the magnetic field inside the sphere?I know that this problem has been solved in many books.But I am trying a different method. Since the magnetic field of a magnetic dipole takes the same form as electric field of an electric dipole, I calculated the electric field inside a sphere (of linear dielectric material of permittivity ε) having a point electric dipole embedded at the center.And then just replaced ε by 1/μ and the electric dipole moment ‘p‘ by the magnetic dipole moment ‘m‘ and of course epsilon naught by one over mu naught. But the answer does not match the correct answer.Is this method of mine wrong?
- The magnetic dipole will magnetize the sphere. This magnetization will create a field of its own. We need to find the net field, that is the resultant field due the dipole and the magnetization of the sphere. My answer is almost the same as that given in Griffiths text except that in the denominator of the second term mu naught and μ are interchanged in my answer
- Q: What are the properties of magnetically hard and soft materials????!!! HELP!?

- Q: The use of magnetic materials, all those products need to use magnetic materials.
- The magnetic material is very simple as the general will be used to make a kind of high-end radio magnetic materials will be used to manufacture wind turbine electric vehicles and some parts of the original space very high-end expensive equipment
- Q: Why magnet losses its magnetic strength on hammering,,, need logical explanition as soon as possibleplzzzzzzzzzzzzzz
- Every single atom has electrons orbiting around the nucleus. This constitutes a tiny current loop which has associated magnetic field with it. In magnetic materials large number of these tiny magnets are aligned in a particular direction and are called domains (in non magnetic materials there is no domain formation all individual magnets are randomly in direction). In magnets (or in presence of a magnet) all these domains are aligned in a particular direction. Hammering, heating etc. breaks this alignment and hence the magnetic strength is lost either partially or completely.
- Q: What actually travels between two poles of a magnet to tranfer the repulsion or attraction force? I would assume it is something to do with positive and negative and if so, which is positive, north or south, and why do magnets give out these particles and why do they affect some materials like iron and nickel but others barely at all? Why does sliding a magnet across a piece of iron make it magnetic? Any other information regarding this sort of thing would be great. Thanks!
- Magnetic forces are forces that arise from the movement of electrical charge. Maxwell's equations and the Biot-Savart law describe the origin and behavior of the fields that govern these forces. Thus, magnetism is seen whenever electrically charged particles are in motion. This can arise either from movement of electrons in an electric current, resulting in electromagnetism, or from the quantum-mechanical spin and orbital motion of electrons, resulting in what are known as permanent magnets. Electron spin is the dominant effect within atoms. The so-called 'orbital motion' of electrons around the nucleus is a secondary effect that slightly modifies the magnetic field created by spin. The magnetic force is actually due[3] to the finite speed (the speed of light) of a disturbance of the electric field which gives rise to forces that appear to be acting along a line at right angles to the charges. In effect, the magnetic force is the portion of the electric force directed to where the charge used to be. For this reason magnetism can be considered to be basically an electric force that is a direct consequence of relativity.
- Q: What is the permeability of ferrite?
- Ferrite saturation magnetization is low (usually only pure 1/3 ~ 1/5), which limits its application in high energy density low power and high power applications.
- Q: But where is current in the case mentioned above?????
- you are grounded there for the current passes through you
