Consider a circular loop of wire lying on the plane of a table. Let an electric current pass through the loop clockwise. The direction of the magnetic field inside is:

• A. perpendicular to the plane of the table pointing into it
• B. always along the tangent to the loop in the same sense of flow of the current
• C. perpendicular to the plane of the table and appearing to emerge out from it
• D. always along the tangent to the loop opposite to the sense of flow of the current
