A magnetic field strength (H) `3xx10^(3)Am^(-1)` produces a magnetic field of induction (B) of `12piT` in an iron rod. Find the relative permeability of iron?

Explanation

To find the relative permeability of iron, we can follow these steps:

### Step 1: Write down the given values
- Magnetic field strength (H) = \(3 \times 10^3 \, \text{A/m}\)
- Magnetic field induction (B) = \(12\pi \, \text{T}\)

### Step 2: Use the relationship between B, H, and μ
The relationship between the magnetic field induction (B), magnetic field strength (H), and permeability (μ) is given by the formula:
