Magnetism and electromagnetismQuestion 868 of 1506

What does a higher permeability tell you about a material?

  1. It passes magnetic flux with more difficulty.
  2. It has higher electrical resistance.
  3. It passes magnetic flux more easily.
  4. It always has a longer length.
Show answer

Correct answer: It passes magnetic flux more easily.

Permeability is the opposite of specific resistance: greater permeability means easier passage of flux.
