A current carrying circular loop lies on a smooth horizontal plane. Can a uniform magnetic field be set up in such a manner that the loop turns around itself (i.e., turns about the vertical axis).

Explanation

To determine whether a current-carrying circular loop can turn around itself (i.e., rotate about its vertical axis) when placed in a uniform magnetic field, we can analyze the situation step by step.

### Step-by-Step Solution:

1. **Understanding the Setup**:
- We have a circular loop carrying a current, placed on a smooth horizontal plane.
- The loop has a magnetic moment (m) associated with it, which is directed perpendicular to the plane of the loop.
