Two magnetic materials A and B have relative magnetic permeabilities of 0.96 and 500 . Identify the magnetic materials A and B .

Explanation

To identify the magnetic materials A and B based on their relative magnetic permeabilities, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Relative Magnetic Permeability**:
- The relative magnetic permeability (\( \mu_r \)) is a dimensionless quantity that indicates how a material responds to a magnetic field compared to a vacuum.
- If \( \mu_r < 1 \), the material is classified as diamagnetic.
- If \( \mu_r > 1 \), the material can be classified as paramagnetic or ferromagnetic, depending on how much greater than 1 it is.
