A. At twice the distance, the magnitude of the field is 4B.
B. At twice the distance, the magnitude of the field is 2B.
C. At twice the distance, the magnitude of the field is B/2.
D. At twice the distance, the magnitude of the field is B/4.
E. At twice the distance, the magnitude of the field remains equal to B.
