Magnetic field in a semi-cut solenoid

Click For Summary
SUMMARY

The discussion centers on the magnetic field behavior of a semi-cut solenoid, specifically addressing the effects of a partially cut covering and core on the magnetic field distribution. It is established that the solenoid's geometry alters the magnetic field, leading to the possibility of it behaving like two separate magnets on either side of the cut. The consensus is that traditional solenoid calculators are inadequate for this scenario, necessitating the use of advanced 3D Finite Element Analysis (FEA) tools such as COMSOL for accurate modeling.

Im just curious as to how the magnetic field would be for a semi cut solenoid as shown in the diagram below.

The Solenoid covering is partially cut and the soft core iron in the solenoid is also cut and the number of windings in the area decrease considerbly..

The winding on either side of the cut is assumed to be equal..

Now at the cut part below the slightly cut iron core and the cut covering of the solenoid... what would be the magnetic field?

Would A, the solenoid form 2 magnets and behave like 2 separate magnets on either side?

or Would B the solenoid forms just one consistent magnetic field..

Which of the 2 would happen? or would something happen?

Anyone willing to help me out?

I would be great full.. :)

Wow, none of the regular solenoid calculators will work with that geometry. I think you'll have to use 3D FEA tools such as COMSOL.
