E and B field.

  1. Aug 12, 2011 #1
    Is the only way to tell that I have a B field, is to take a test charge and place it stationary and see that it doesn't move? And then fire a test charge and see that it gets deflected when it is moving at a speed. And if my test charge moved from rest I would know there is an E field.
    Is this the only way to tell the difference between E and B fields. At least relative to me.

    The old fashioned way is to wave a conductor around and see if you generate a current.

    If i moved a conductor around in an E field . Wouldn't it create a small current for a little while until it polarized the material.
