How does a magnetic field create electricity? How a magnetic field is produced by moving charges. How can a magnetic field produce an electric current? When was the cathode ray tube invented? How are electromagnetic waves propagated? How do electrons create a magnetic field?
Why is a magnetic field produced due to a current? How did the greenhouse effect start? Why electromagnetism is important? Why is electromagnetism important? How does carbon dioxide affect plants' stomata? How do phytoplankton blooms affect our lives?
In a chime doorbell, the audible chime is produced when a metal piston strikes a tone bar. The force that moves the piston is the magnetic field of a solenoid that receives electric current when the doorbell is pushed.Cite This Article MLA Nicholson, Joseph. "How Does A Solenoid Work?" ...
The strength of a magnet in an MRI system is rated using a unit of measure known as a tesla. Another unit of measure commonly used with magnets is the gauss (1 tesla = 10,000 gauss). The magnets in use today in MRI systems create a magnetic field of 1.5-tesla to 7.0-tesla, or ...
However, when collapsing down to small scales magnetic fields become superstrong exceeding any limits which can be reached in the laboratory. A brief review and discussion is given on the absolute limitation to the magnetic field strengths which can be obtained during such collapses....
1) The Earth’s magnetic field is hella weak 2) it’s so big and roughly uniform that there’s no reason for a magnet to go one direction or the other 3) floating a magnet in a magnetic field is a delicate balancing act even in the best circumstanc...
A magnetic field was created below the airplane to sweep magnetic mines in the water below it. Because the Germans never placed mines near our coast, however, this plane was never used. The basic technology for electronic computers began in 1907 in the United States, when Lee DeForest ...
Electromechanical Process:When a conductor moves in amagnetic fieldand the conductor cuts the fieldflux lineselectricity is produced in the conductor. Depending on this principle allelectrical generatorswork such asDC generators,alternators, and all kinds of dynamos. ...
On Earth, the magnetic field is produced by a process of dense materials on the surface starting to cool and sinking into the planet's interior while hotter materials rise from the interior to the surface. The resulting convection maintains this movement and mixing of materials. A magnetic dipol...
有磁场的物体 And where there is a body with a magnetic field, 就有磁极 there are magnetic poles, 这是物体可以逃逸的地方 and thats where things can escape. 物质纠缠在一起,螺旋上升 It gets wound around, spiraled up, 并被推进喷射流中 and shoved up into a jet. 这个过程中的压强非常高 ...
