Magnetism - Magnetic Fields, Forces, Materials: All matter exhibits magnetic properties when placed in an external magnetic field. Even substances like copper and aluminum that are not normally thought of as having magnetic properties are affected by the
磁场与磁通量Magnetic Forces And Magnetic Fields.
Magnets twist if the magnetic fields are not alignedMagnets not only exert a force on one another, they also can exert a twisting moment as well. If you have a single magnet in free space, the magnetic field looks something like the image at left. The color is related to the strength ...
Magnetic field lines are a visual tool used to represent magnetic fields. They describe the direction of the magnetic force on a north monopole at any given position The density of the lines indicates the magnitude of the field. Taking an instance, the magnetic field is stronger and crowded ne...
so the total magnetic field is the vector sum of the fields from all magnetic sources nearby. ! Consider two solenoids producing nearly uniform fields:physics 112N 16physics 112N 17! magnetic fields produce a force on charged particles that are moving through them ! experiments show that the ...
field intensity,field strength- the vector sum of all the forces exerted by an electrical or magnetic field (on a unit mass or unit charge or unit magnetic pole) at a given point in the field Based on WordNet 3.0, Farlex clipart collection. © 2003-2012 Princeton University, Farlex Inc...

It is the basic force responsible for such effects as the action of electric motors and the attraction of magnets for iron. Electric forces exist among stationary electric charges; both electric and magnetic forces exist among moving electric charges. The magnetic force between two moving charges...
