How could you tell whether moving electrons in a cf k knk76dhe5j:*ks4nrv5 ux1ertain region of space are +eiu9 nyy+x wc.gl,z-slg ) k9being deflected by an electric k+-xle ,y+yzg )wnl.s99ug icfield or by a magnetic field (or by both)?
参考答案: If
the moving electrons are changing speed as they are being deflected, then an
electric field is present. This will be
the case whether or not a magnetic field exists in the same region of
space. If the moving electrons are being
deflected but they are not changing speed, then only a magnetic field is
present.
