Mention two characteristic properties of the material suitable for making core of a transformer.

Explanation

To answer the question regarding the characteristic properties of the material suitable for making the core of a transformer, we can break it down into the following steps:

### Step-by-Step Solution:

1. **High Resistivity**:
- The material used for the core of a transformer should have high resistivity. This is important because a high resistivity helps to minimize the losses due to eddy currents. Eddy currents are loops of electric current that are induced within conductors by a changing magnetic field, which can lead to energy loss in the form of heat. Therefore, a material with high resistivity reduces these losses and improves the efficiency of the transformer.

2. **Low Hysteresis Loss**:
