Magnetic Field Distribution (2)

Question 1

The strength of a magnetic field produced by the conductor is dependant on the type of conductor ____, the ____ and it’s _____.

Answer 1

material, the size and it’s shape.

Question 2

Characteristics of a Direct Current passing through a Solid Non-Magnetic Conductor

Answer 2

• field strength = 0 at center and max at outer surface
• field strength directly proportional to size of conductor
• field strength outside conductor will decrease as distance from center increased

Question 3

Characteristics of a Direct Current passing through a Solid Magnetic Conductor

Answer 3

• field strength inside conductor is greater than it is in a non-magnetic conductor
• field strength is greatest below conductor surface
• field strength on outer surface = that of a non-magnetic conductor
• field strength is dependant on conductor permeability

Question 4

Characteristics of a Direct Current passing through a Hollow Non-Magnetic Conductor

Answer 4

• field strength inside hollow portion will be 0
• field strength is greatest at the conductors outer surface
• outer conductor surface field strength is the same as it would be on a solid non-magnetic conductor

Question 5

Characteristics of a Direct Current passing through a Hollow Magnetic Conductor

Answer 5

• field strength in hollow portion of conductor = 0
• field strength is greatest within conductor (below surface)
• field strength on inner surface is weak
• field strength on outer surface is = field strength on outer surface on a solid magnetic conductor
