Hey.
I am learning about electromagnetism and have been told that a moving charge creates a magnetic field which can then interact with an external magnetic and produces a force on the moving charge which is the basis of the motor effect etc.
I am now onto electromagnetic induction and am told that moving a conductor or an external magnetic field relative to one another induces current within the wire. This is explained in terms of the motor effect by moving the conductor and leaving the external field be. However, moving the external field and leaving the conductor be still produces the same effect.
This implies to me that charges always create a magnetic field regardless of whether they are moving. Otherwise, the explanation of electromagnetic induction is missing something crucial.
Any pointers would be much appreciated.
