State the SI unit and dimensions of magnetic flux.

Explanation

To determine the SI unit and dimensions of magnetic flux, we can follow these steps:

### Step 1: Understand the Definition of Magnetic Flux
Magnetic flux (Φ) is defined as the product of the magnetic field (B) and the area (A) through which the field lines pass. Mathematically, it is expressed as:
\[ \Phi = B \cdot A \]
