WebSep 12, 2024 · The magnetic field lines of the infinite wire are circular and centered at the wire (Figure 12.3. 2 ), and they are identical in every plane perpendicular to the wire. Since the field decreases with distance from the wire, the spacing of the field lines must increase correspondingly with distance. WebFeb 14, 2024 · A rod with circular cross-section area 2 cm2 and length 40 cm is wound uniformly with 400 turns of an insulated wire. If a current of 0.4 A flows in the wire windings, the total magnetic flux produced inside windings is 4π x 10-6 Wb. The relative permeability of the rod is (Given : Permeability of vacuum μ0 = 4π x 10-7 NA-2) (1) 12.5 (2) 32/5
WebFeb 28, 2024 · A circular cross section core will naturally have a smaller inner radius and, because of this, it will tend to magnetically saturate a little bit more at that inner radius … WebThe torsion constant is a geometrical property of a bar's cross-section which is involved in the relationship between angle of twist and applied torque along the axis of the bar, for a homogeneous linear-elastic bar. The torsion constant, together with material properties and length, describes a bar's torsional stiffness.The SI unit for torsion constant is m 4.
