Hysteresis (1)

Question 1

horizontal line on the hysteresis loop represents:

Answer 1

Magnetizing force

H

Question 2

vertical line on the hysteresis loop represents:

Answer 2

Flux density

B

Question 3

a wide loop will exhibit:

Answer 3

• low permeability
• high retentivity
• high coercive force
• high reluctance
• high residual magnetism

Question 4

a narrow loop will exhibit:

Answer 4

• high permeability
• low retentivity
• low coercive force
• low reluctance
• low residual magnetism

Question 5

Residual magnetic fields are effected by the permeability related to the carbon content and alloying of the material -

Answer 5

a high carbon content will have a low permeability and will retain more magnetic flux
