Question

the measure of a materials ability to be magnetized is called _______
a. residual magnetism
b. reluctance
c. saturation
d. permeability

Explanation:

Define the core concept of magnetization ability

The question asks for the term that describes a material's ability to become magnetized or allow magnetic lines of force to pass through it. This is a fundamental property of Magnetic Materials.

Analyze the given options

• a. residual magnetism: This refers to the magnetization left behind in a ferromagnetic material after an external magnetic field is removed.
• b. reluctance: This is the opposition that a material offers to the passage of magnetic flux, analogous to electrical resistance.
• c. saturation: This is the state reached when an increase in an applied external magnetic field cannot increase the magnetization of the material any further.
• d. permeability: This is the measure of the ease with which a magnetic field can be established in a material, representing its ability to be magnetized.

Identify the correct term

Since permeability measures how easily a material can support the formation of a magnetic field within itself, it represents the material's ability to be magnetized. Therefore, option d is the correct choice.

Answer:

• a. residual magnetism
• b. reluctance
• c. saturation
• d. permeability (Correct answer)
