pg.576 #32: Can an electron be set into motion with a magnetic field? and explain.
Answer:
Not if the magnetic field is static. An electron (a charge) at rest only has an electric field and so requires another electric field to create a force that will move the electron. But a changing magnetic field causes a magnetic field to form around the electron which will create a deflecting force.
So, if you change the magnetic field (e.g. change its intensity, or move it around) that will create a deflecting force that will set the electron in motion. Another way of looking at it, is moving the magnetic field near a static charge is basically the same thing as moving a charge through a static magnetic field, described in section 36.6. In either case the charge APPEARS to be moving through a magnetic field.
