The electric field
... CT –2 - Which of the following statements is (are) true? A. When there are more electric field lines leaving a gaussian surface than entering it then there is a net negative charge enclosed by the surface. B. Gauss's law can be used to find the electric field if the total charge inside a closed sur ...

... The magnet used in the activity is not very strong. And not many turns of wire are used to make the coil. With a current detector you can detect a current produced by such a generator. But the current isn't even strong enough to light a bulb. How can a stronger current be made? The stronger the magn ...

... other. As they flow in opposite directions, they are mutually attenuated in the overlapping region, and the fall time of the magnet is reduced. So it follows that there must be an arrangement with a maximal fall time. Summary The temporal decay, or dissipation of eddy currents is caused by the resis ...

... Just as magnets are surrounded by magnetic fields, electric charges are surrounded by electric fields. An electric field enables charges to exert forces on each other even when they are far apart. An electric field exists around an electric charge even if the space around it contains no matter. ...
