An ideal solenoid has a core of relative
permeability 600 and its winding has 1500
turns per meter. If a steady current of 2A is
passed through its winding find (i) the
field
strength H (ii) the
magnetic
magnetization M, (iii) The magnetic induction
B within the solenoid. Assume that M, is
directly proportional to H and single valued.
A closely wound solenoid of 2000 turns and area of cross-section 1.6×10 −4 m 2 carrying 4.0 A current, is suspended through its centre, thereby allowing it to turn in a horizontal plane.
What is the magnetic moment associated with the solenoid?
What should be the length of an ideal solenoid consisting of 1250 turns for the magnetic field in its interior to be 0.025 T? A current of 2.0 A is flowing through the solenoid.
