Question

The magnitude of the magnetic field at a certain distance from a long, straight conductor is represented by B. What is the magnitude of the magnetic field at twice the distance from the conductor? O At twice the distance, the magnitude of the field is B/2. O At twice the distance, the magnitude of the field is B/4. O At twice the distance, the magnitude of the field is 2B. At twice the distance, the magnitude of the field remains equal to B O At twice the distance, the magnitude of the field is 4B.
