Creating a Magnetic Field Like Pic-2: Possible?

AI Thread Summary
Creating a magnetic field like the one depicted in pic-2 is deemed impossible, as it resembles half of a monopole. While a solenoid generates a magnetic field, it does not create a one-way field as shown in the image. The magnetic field of a current-carrying solenoid does loop back, adhering to Gauss' law for magnetism, which states that magnetic fields must have zero divergence. The proposed design in pic-2 would violate this fundamental principle. Therefore, the discussion concludes that such a magnetic field cannot be realized.

solenoid? approximately i guess
 
Uh... NO.
This cannot be done.
 
Looks like half of a monopole.

Exceedingly impossible.
 
issn't the B-field of a current carrying solenoid something like that?

Locally, yes, but it does loop around to the other end of the solenoid.

That is, If you look very close to one of the ends of the drawing in fig 1, it looks like fig 2.
 
The one way field shown violates Gauss' law for magnetism, i.e. it has non-zero divergence. Solenoids do not violate Gauss' law for magnetism, i.e. they have zero divergence everywhere.
