What are units of magnetic permeability?

Explanation

To find the units of magnetic permeability, we can start from the relationship between magnetic field (B), magnetic permeability (μ), and magnetic dipole moment (m).

### Step-by-Step Solution:

1. **Understand the Relationship**:
The magnetic field \( B \) can be expressed in terms of magnetic permeability \( \mu \) and magnetic dipole moment \( m \). The equation can be given as:
\[
B = \frac{\mu}{4\pi} \cdot \frac{m}{r^2}
