A magnetic material X has a relative permeability slightly greater than unity. Another material Y has a relative permeability less than unity. Depict the nature of materials X and Y. Also state whether their susceptibilities will be positive or negative.

Explanation

To solve the problem, we need to analyze the properties of the two magnetic materials, X and Y, based on their relative permeability values.

### Step-by-Step Solution:

1. **Understanding Relative Permeability**:
- Relative permeability (μr) is a measure of how much a material can be magnetized in response to an applied magnetic field compared to a vacuum.
- If μr > 1, the material is classified as paramagnetic.
- If μr < 1, the material is classified as diamagnetic.
