select the best answer for the question.

1. which of the following would experience induced magnetism most easily?

○ a. aluminum
○ b. air
○ c. permalloy
○ d. copper

□ mark for review (will be highlighted on the review page)

<< previous question next question >>

Explanation:

To determine which material experiences induced magnetism most easily, we analyze the magnetic properties of the options:

• Option A (Aluminum): Aluminum is a non - magnetic material (paramagnetic with very weak magnetic response), so it does not easily get induced magnetism.
• Option B (Air): Air is a non - magnetic medium and has no significant magnetic properties to be induced magnetically.
• Option C (Permalloy): Permalloy is a type of soft magnetic material with very high magnetic permeability. Materials with high magnetic permeability are very easy to be magnetized and thus experience induced magnetism easily.
• Option D (Copper): Copper is a non - magnetic material (diamagnetic with a very weak and opposite magnetic response), so it does not easily get induced magnetism.

Answer:

C. Permalloy
