According to Ampère's circuital law, the circulation of magnetic field in a closed curve is equal to ........ Times the total current enclosed within the closed curve.

Answer

To answer the question regarding Ampère's circuital law, we need to understand the relationship it describes between the magnetic field and the current flowing through a closed loop.

### Step-by-Step Solution:

1. **Understanding Ampère's Circuital Law**:
Ampère's circuital law states that the circulation of the magnetic field (B) around a closed loop is proportional to the total current (I) enclosed by that loop. Mathematically, it can be expressed as:
\[ \oint \mathbf{B} \cdot d\mathbf{L} = \mu_0 I_{\text{enclosed}} \]
where \(\oint \mathbf{B} \cdot d\mathbf{L}\) is the line integral of the magnetic field around the closed loop, \(\mu_0\) is the permeability of free space, and \(I_{\text{enclosed}}\) is the total current passing through the loop.

2. **Identifying the Proportionality Constant**:
From the equation, we can see that the circulation of the magnetic field is equal to \(\mu_0\) times the total current enclosed. Therefore, the answer to the question is:
\[ \text{the circulation of magnetic field in a closed curve is equal to } \mu_0 \text{ times the total current enclosed.} \]

3. **Conclusion**:
Thus, according to Ampère's circuital law, the circulation of the magnetic field in a closed curve is equal to \(\mu_0\) times the total current enclosed within that closed curve.

### Final Answer:
The circulation of the magnetic field in a closed curve is equal to **\(\mu_0\)** times the total current enclosed within the closed curve.
