SUMMARY

The discussion focuses on the methods for distinguishing between electric (E) and magnetic (B) fields. It establishes that one effective way to identify a B field is by placing a test charge stationary and observing that it does not move, while a moving test charge will experience deflection, indicating the presence of a B field. Additionally, the conversation highlights that moving a conductor within an E field can generate a temporary current until the material polarizes, providing insight into the behavior of charges in different fields.

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.
