The correct Answer is:
To solve the problem of determining the position of a point on the axis of a circular loop carrying a current when it is replaced by an equivalent magnetic dipole, we can follow these steps: ### Step-by-Step Solution: 1. **Understanding the Setup**: - We have a circular loop that carries a current \( I \). This loop generates a magnetic field around it. - When we talk about an equivalent magnetic dipole, we can think of it as having a north and south pole, similar to a bar magnet. 2. **Identifying the Axis**: - The axis of the circular loop is the line that passes through the center of the loop and is perpendicular to its plane. - The magnetic dipole's axis is also aligned with this line when the dipole is placed at the center of the loop. 3. **Position of the Point**: - A point located on the axis of the loop is in line with the magnetic dipole's axis. This means that the point is directly in front of one of the poles of the magnetic dipole. 4. **Determining the Position Type**: - The term "end-on position" refers to a point that is aligned with the magnetic dipole's axis, meaning it is located along the line extending from the north pole to the south pole. - In contrast, a "broadside-on position" would be a point that is perpendicular to this axis. 5. **Conclusion**: - Since the point we are considering is on the axis of the loop (and thus also on the axis of the magnetic dipole), it is indeed in an "end-on position". ### Final Answer: The correct option is **end-on position**. ---
