Magnetic force, attraction or repulsion that arises between electrically charged particles because of their motion. It is the basic force responsible for such effects as the action of electric motors and the attraction of magnets for iron. Learn more abo
Magnetic fields may be represented by continuous lines of force ormagnetic fluxthat emerge from north-seekingmagnetic polesand enter south-seeking magnetic poles. The density of the lines indicates the magnitude of the magnetic field. At the poles of a magnet, for example, where the magnetic fiel...
Magnetism is a force of nature produced by moving electric charges. Sometimes these motions are microscopic and inside of a material known as magnets. Magnets, or the magnetic fields created by moving electric charges, can attract or repel other magnets, and change the motion of other charged ...
Magnetism Lesson for Kids: Definition & Facts from Chapter 6 / Lesson 33 32K There are various types of magnetic materials and magnets can both attract and repel each other. Learn more about the properties of magnetism and how the Earth's magnetic field ...
Everybody has their own way of doing things and trying to force your way down their throats is just wrong. That thinking is the kind of thinking that starts world wars because people solely are different from you. Come on Mom’s we’re supposed to be having each other’s backs and ...
Basic to magnetism aremagnetic fieldsand their effects on matter, as, for instance, thedeflectionof moving charges and torques on other magnetic objects. Evidence for the presence of a magnetic field is themagnetic forceon charges moving in that field; theforceis at right angles to both thefi...
When anelectronmoving in an atomic orbit is in amagnetic fieldB, theforceexerted on the electron produces a small change in the orbital motion; the electron orbit precesses about the direction ofB. As a result, each electron acquires an additionalangular momentumthat contributes to the magnetizati...
Inductance, property of a conductor (often in the shape of a coil) that is measured by the size of the electromotive force, or voltage, induced in it, compared with the rate of change of the electric current that produces the voltage. A steady current pr
Charged particles tend to spiral about a magneticline of force. It is necessary that these particle trajectories do not intersect the bounding wall. Simultaneously, thethermal energyof all the particles exerts an expansive pressure force on the plasma. For the plasma to be in equilibrium, themagne...
