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...
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
Ideal for students, educators, or anyone with a keen interest in physics, this quiz offers clear and concise questions that test and build your understanding of magnetic principles. Get ready to align your knowledge with scientific facts and discover the intriguing world of magnetism. Take the ...
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 ...
but it is necessary to keep a calm and rational mind and examine the facts: And the facts are that there is no working model of the device, there is no testability to the theory propogated to explain its supposed workings, and there is no substantial mathematical basis for the assertions ...
Magnetic fields force moving electrically charged particles in a circular or helical path. This force—exerted on electric currents in wires in a magnetic field—underlies the operation of electric motors. (For more information about magnetic fields, see magnetism. Discover how wireless electricity ...
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...
Several conditions must be satisfied for the fluid motion to produce a magnetic field. First, the fluid must be electrically conducting. Second, a magnetic field must be present, possibly as a relict of the initial formation of the body. Third, some force must introduce twists into the fluid...
force, responsible for theenergyreleased innuclear fusion, and theweak force, observed in theradioactivedecay of unstable atomic nuclei. In particular, the weak and electromagnetic forces have been combined into a common force called theelectroweakforce. The goal of many physicists to unite all of...
The top panel shows that the increase in the value of the magnetic charge of the test particle makes the effective potential stronger, which strengthens the attractive force between the black hole and test particle, which in turn makes the ISCO radius bigger (which is discussed later). The ...
