An external magnetizing force is placed near a demagnetized piece of iron. What happens to the
domains within the iron? - correct answer The domains align with the external force.
When a magnetizing force is increased on a piece of iron, the. Monetizing strength of the iron increases
to a limit. Which of the following terms describes this limit? - correct answer Magnetic stauration
Why is the permeability of a material important? - correct answer A material's ability to fit more lines of
flux creates a stronger magnet.
Relays rely on electromagnetism for their operation. What is used with a leveling switch to provide
magnetic operation? - correct answer Permanent magnet
The solenoid in a hydraulic control valve has a core of iron. Which characteristics of magnetic lines of
force enables the solenoid to operate when power is applied. - correct answer The elasticity of the flux
