Answer

To analyze the given statements regarding the Poynting vector, let's break down the solution step by step.

### Step 1: Understanding the Poynting Vector
The Poynting vector (denoted as **S**) is defined as the vector that represents the directional energy flux (the rate of energy transfer per unit area) of an electromagnetic field. It is mathematically expressed as:

\[ \mathbf{S} = \frac{1}{\mu_0} \mathbf{E} \times \mathbf{B} \]

where:
- \(\mathbf{E}\) is the electric field vector,
- \(\mathbf{B}\) is the magnetic field vector,
- \(\mu_0\) is the permeability of free space.

### Step 2: Evaluating Statement 1
**Statement 1** claims that the magnitude of the Poynting vector represents power per unit area.

- The magnitude of the Poynting vector indeed represents the power per unit area, as it quantifies how much electromagnetic energy is passing through a unit area in a given time. Therefore, **Statement 1 is true**.

### Step 3: Evaluating Statement 2
**Statement 2** states that the direction of the Poynting vector gives the direction of propagation of electromagnetic waves.

- The direction of the Poynting vector is given by the cross product of the electric field and magnetic field vectors (\(\mathbf{E} \times \mathbf{B}\)). This direction indicates the flow of energy in the electromagnetic wave, which corresponds to the direction in which the wave propagates. Thus, **Statement 2 is also true**.

### Conclusion
Both statements are true:
- **Statement 1**: True (Magnitude of Poynting vector represents power per unit area).
- **Statement 2**: True (Direction of Poynting vector gives the direction of propagation of electromagnetic waves).

### Final Answer
Both statements are correct.
