A current carrying loop free to turn is placed in a uniform magnetic field. What will be its orientation relative to the rection of magnetic field in the equilibrium state?

Explanation

To solve the problem, we need to determine the orientation of a current-carrying loop in a uniform magnetic field when it reaches an equilibrium state. Here’s a step-by-step solution:

### Step 1: Understand the Concept of Torque
In a magnetic field, a current-carrying loop experiences a torque. The torque (\( \tau \)) acting on the loop is given by the equation:
\[ \tau = \mathbf{m} \times \mathbf{B} \]
where \( \mathbf{m} \) is the magnetic moment of the loop and \( \mathbf{B} \) is the magnetic field vector.
