If the radius of a circular loop carrying current is doubled, how does the magnetic field at the center change?
It doubles
It halves
It remains the same
It quadruples
The magnetic field at the center of a circular loop is inversely proportional to the radius; thus, doubling the radius halves the magnetic field.
