Electromagnetic force creates electromagnetic field.
Explanation:
Electromagnetic force acts between charged particles and this force is the combination of all electrical and magnetic forces. On the other hand, the electromagnetic field is detected by the force it exerts on other magnetic particles and moving electric charges. So, electromagnetic field is created by electromagnetic force. Without this force there cannot be any electromagnetic field.
