What is magnetic flux linked with a coil or N turns or are cross section A held with its plane parallel to the field?

Explanation

To find the magnetic flux linked with a coil of N turns and a cross-sectional area A held with its plane parallel to the magnetic field, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Magnetic Flux**:
The magnetic flux (Φ) linked with a coil is defined as the product of the magnetic field (B), the area of the coil (A), and the cosine of the angle (θ) between the magnetic field and the normal (perpendicular) to the surface of the coil.
\[
\Phi = N \cdot B \cdot A \cdot \cos(\theta)
