What would be the magnetic field of a solenoid if the wire of the solenoid itself is made up of another solenoid? I would be glad to hear any explanation about it.
Astronuc said:One would have an azimuthal field (from the smaller diameter windings) superimosed on an axial field (of the larger windings).

Vanadium seems to have a different picture in mind, so yes some clarification by the OP would be helpful.
The magnetic field B is continuous, it exists both inside and outside a solenoid. The return flux for the field inside a solenoid is outside.Bob_for_short said:I think two magnetic fields will be in this system: one in the primary coil and another in the secondary. They will not be superimposed but separated - confined inside the corresponding coils.
Bob, can you describe the main features of the field? Or at least confirm/dispell my suspicions about the field, that it:Bob S said:Smythe "Static and Dynamic Electricity" 3rd edition pages 296-297 solves the field in a helical solenoid.

Definitely a field within the smaller outer solenoid. I keep going back and forth on whether there is an appreciable field inside the larger solenoid. At first I thought not, since it lies outside the outer solenoid. But now I am thinking that the usual argument with takingBob_for_short said:I think two magnetic fields will be in this system: one in the primary coil and another in the secondary. They will not be superimposed but separated - confined inside the corresponding coils.
There is no effect on the flowing liquid (conducting) metal in a constant B field along the axis of a solenoid, in part because the direction of flow is parallel to the field and dB/dt = 0. There are propulsion systems using crossed E and H fields perpendicular to the desired direction of flow, using the Lorentz force F = l(I x B) . See paragraph 3.1.1 inmervk_16 said:now how if the same solenoid (which is made up of another solenoid) i.e the 1st solenoid is hollow in the inside and we have a liquid metal flowing within it? (considering fluidity, waves, magnetohydrodynamics)
1. An axial field within the large main coil, of strength
B = μo n1 I
where n1 is the turns-per-length of the main coil.
A solenoid is a coil of wire that produces a magnetic field when an electric current is passed through it.
When current flows through a solenoid, it creates a magnetic field due to the alignment of the individual magnetic fields of the electrons in the wire.
The strength of a solenoid's magnetic field is affected by the number of turns in the coil, the current flowing through the coil, and the material of the core.
Yes, the direction of a solenoid's magnetic field can be reversed by changing the direction of the current flowing through the coil.
The magnetic field of a solenoid can be measured using a magnetic field meter or a compass. The strength of the field can also be calculated using mathematical equations based on the factors affecting its strength.
