Answer 1

Are the laws still valid when the magnetic fields are changing? Specifically B = 0 at certain point in time and then B = x Teslas.

In general, is Faraday's law applied when magnetic field are not static, I understand that ?
B is changing so how is EMF calculated?

Example:

A conductor moves from point A to B, within that displacement a point X has a magnetic field = 1 Tesla, and then goes back to 0. How can EMF be calculated here?
I assume motional EMF can't be used here since there is no change in distance to calculate velocity?
