What is the relation between relative magnetic permeability and magnetic susceptibility?

Explanation

To find the relation between relative magnetic permeability (μR) and magnetic susceptibility (χm), we can follow these steps:

### Step-by-Step Solution:

1. **Define the Terms**:
- Relative Magnetic Permeability (μR): This is a dimensionless quantity that represents how much a material can be magnetized compared to the vacuum. It is defined as the ratio of the permeability of the material (μ) to the permeability of free space (μ0).
- Magnetic Susceptibility (χm): This is a measure of how much a material will become magnetized in an applied magnetic field. It is also a dimensionless quantity.
