Two parallel, long, straight conductors lie on a smooth plane surface. Two other parallel conductors rest on them at right angles so as to form a square of side a initially. A uniform magnetic field B exists at right angles to the plane containing the conductors. Now they start moving out with a constant velocity (v).
Will the current be time dependent?

Explanation

To solve the problem step by step, we will analyze the situation involving the conductors, the magnetic field, and the induced electromotive force (emf) as well as the current flowing through the conductors.

### Step 1: Understand the Configuration
We have two parallel long conductors lying on a smooth plane surface, and two other parallel conductors resting on them at right angles, forming a square of side length \( a \). A uniform magnetic field \( B \) is present perpendicular to the plane of the conductors.

**Hint:** Visualize the arrangement of the conductors and the magnetic field to understand how they interact.
