Manipulating this kind of electromagnet?
(OP)
This is an electromagnet that has both poles on it's surface. Example .
When it's surface is in direct contact to a ferromagnet it generates forces up to 480 lb.
Now it's manufacture states that it's not possible to create a repulsive force... I would disagree and would ask you if this is true?
Assuming the surface has both N & S poles, bringing an equal electromagnet like it, and orienting it in such a way N meets N and S meets S, there should be a strong repulsive force( Assuming Power input on both is the same).
Or am I missing something here?
The manufactures statement: Can electromagnets be used to repel as well as attract?
As they are sold, minimal to no repel can be achieved as they are designed to attract. What is needed to repel is a coil around an iron core with no outer shell. This configuration places a north pole at one end of the iron core and a south pole at the opposite end. The electromagnets as they are sold have a south pole and north pole on the same end. One pole is on the outside ring or shell and the other pole is located on the center post or core.
Can they be repelled?
And is the repulsive force near the attractive force?

As the manufacturer explains, you would need to remove the shell to have only one pole on the coil face.

RE: Manipulating this kind of electromagnet?
Is there a specific name to this configuration? That I can research more about?
I'm imagining two poles on one side, I understand that point. However, why can't the repulsive force be achieved here using an identical product?
Here is why I'm confused...there is a magnetic field, and it's known that if we introduce a pole to a similar pole a repulsive force will emerge.
If this is experimented what might be the results?

RE: Manipulating this kind of electromagnet?
When you place two identical electromagnets close together N to N, S to S, you would probably still get an attractive action, but will be off-center (mis-match) since N will find S, and S to N. If you can force two magnets against perfectly in a line, you could get a repulsive force. I would guess the repelling force is smaller than attraction.

Is it it possible to build an electromagnet that could repel( similar electromagnets) with large forces using the same materials however in a different designs?

RE: Manipulating this kind of electromagnet?
@IRstuff if the shell is removed do you think the performance would drop greatly when it is able to repel opposing poles?

http://armymedical.tpub.com/md0950/md09500047.htm shows that there are more field lines participating in attraction than in repulsion
