Okay so this forum is related to the previous one. See solenoid best adjustment .

I am thought of using solenoid as a electromagnet , by generating south and north pole . But i found out that magnetic field produce is not enough so as I can generate a coil at say 26 cm from the electromagnet . The distance between the two poles is 50 cm. I found out that it is not enough at the center of this distance . I am driving my output at say 25 cm from the poles.

So I thought because the magnetic field is uniform at any given distance inside the solenoid why don't I directly insert the coil inside a solenoid . So now I am adjusting my coil and inserting it into a solenoid. This solenoid has iron core . So I would cut out the size of a coil piece of iron core at perpendicular to the length of the cylinder which has wire over it on the cylinder type electromagnet.

The length of the solenoid comes out to be 50 cm . Number of turns is 200 , current is 3 A . The magnetic field that will be achievable is maximum let's say 2 Tesla . Because of saturation the theoreical magnetic field and the actual differs. Permeability is 0.0063. or 0.25 if annealed in H . Now I cut out a piece enough to accommodate the coil . But I cut it from the middle and not the whole cross section area . Then i inserted the coil there . I have not cut it all the way through . Just enough so that my coil is inserted .

I wanted to know if I am using this process then what would be my cost for such a iron core? Would there be any flux in the pieces I have cut or would it simply pass away from the iron ore magnetic circuit ? Would the air that would present in the pieces where coil is present , would it act as a reluctant to the magnetic circuit ? Magnetic circuit here means then solenoid . As the magnetic field inside a solenoid is independent of diameter . I can also use a big diameter iron ore but I am worrying about such a iron ore cost and also the wasteful of that mineral . Any help would be appreciated .

. Would a flux cut through the coil that's what I am asking , provided that magnetic field is given by the formula of inside of a solenoid magnetic field .
