How does an electric field create a magnetic field and relativity

[scilearner]

Hello everyone,

 

How does an electric field create a magnetic field. If we move at the same speed in the direction of the electric field would we see a magnetic field. Would we still see it because it is perpendicular but we would see the electric field not moving so not sure.

 

Thanks!!
