Is it possible to concentrate/focus/channel a magnets magnetic field into a single, straightforward direction?


You can guide the field of a magnet with metals such as aluminum or copper. The field will tend to remain within the metal. One example of this is the core metal used within transformers. Regardless of how you set things up, however, the field does eventually have to curl back to the other end of the magnet. All magnetic fields form complete loops. You can use cores and other magnets to make the field straight within a certain space, but not everywhere.

Dr. Ken Mellendorf

It is possible to concentrate the magnetic field between two poles of a magnet but it is not possible to send the magnetic field, in a confined beam, out into free space.
