Question

Ferromagnetic material used in transformers must have_______.
Fill in the blank with the correct answer from the options given below.

• A. Low permeability and High Hysteresis loss
• B. High permeability and Low Hysteresis loss
• C. High permeability and High Hysteresis loss
• D. Low permeability and Low Hysteresis loss

Answer 1

The Correct Option is B

Let's analyze the properties of ferromagnetic materials used in transformers.

1. Permeability:

Permeability is a measure of how easily a material can be magnetized. For transformers, we want the core material to easily allow the magnetic flux to pass through it. Therefore, we need high permeability.

2. Hysteresis Loss:

Hysteresis loss is the energy dissipated as heat due to the repeated magnetization and demagnetization of the core material in each AC cycle. For transformers, we want to minimize this loss to improve efficiency. Therefore, we need low hysteresis loss.

Therefore, ferromagnetic material used in transformers must have high permeability and low hysteresis loss.

The correct answer is:

Option 2: High permeability and Low Hysteresis loss
