16 The correct answer is D) directly proportional to r and is directed in the clockwise direction when viewed into the page. This is based on the right-hand rule, which states that if you wrap your right hand around a wire with your thumb pointing in the direction of the current, the direction of your fingers will indicate the direction of the magnetic field. When viewed into the page, the magnetic field will be clockwise around the wire, and its strength will be directly proportional to the distance from the wire (r).
