Just as an electric field is described by drawing the electric lines of force, in the same way, a magnetic field is described by drawing the magnetic lines of force. When a small north magnetic pole is placed in the magnetic field created by a magnet, it will experience a force. And if...
Magnetic lines of force, or flux, are measured in Webers (Wb). In electromagnetic systems, the flux relates to the current. A field's strength, or the density of the flux, is measured in tesla (T) or gauss (G). One tesla is equal to 10,000 gauss. You can also measure the field...
Science defines magnet as an object that is surrounded by a magnetic field and has the property, either natural or induced to attract. We have a magnetic field around us, and the ability to attract. That means we are magnets. And like magnets, we too we have both negative and positive ...
is why the magnetic field is orthogonal to the electrical field. One is caused by linear motion, and the other is caused by the spin on the particle in linear motion. The forward motion of the photon causes the electrical force or field, the spin of the photon causes the magnetic force ...
magnetic field, an electric force is magnetic field, an electric force is exerted on it. If a charged particle exerted on it. If a charged particle moves at an angle to a magnetic field, moves at an angle to a magnetic field, the magnetic force acting on it will the magnetic force...
The track is actually an array of electrically shorted circuits containing insulated wire. In one design, these circuits are aligned like rungs in a ladder. As the train moves, a magnetic field repels the magnets, causing the train to levitate. There are currently three Inductrack designs: Ind...
What is Earth's magnetic field made of? How to create a magnetic field without electricity. What is the magnitude of Earth's magnetic field? What creates a magnetic field? Is gravity a magnetic field? Why is the magnetic force perpendicular to the magnetic field?
4.Electric charge is invariant while relativistic mass isn't 2.这条问,把磁铁靠近冰箱的门,磁铁会粘在门上,为什么说磁铁是永久的磁体而冰箱不是.其实是要求你知道source of a permanent magnetic field 的定义. 答案是:Permanent magnets are objects that produce their own persistent magnetic fields.All pe...
