A permanent magnet would help focus a magnetic field. In fact, that is one way to old tube-type television sets are focused – the glue permanent magnets to the back of the picture tube. But to do things correctly, you need another magnetic field – an ELECTROMAGNET. This COULD be as simple as an electric field running through a coil of wire. This IS how the old tube-type televisions an computer monitors are controlled. First, understand that the electromagnet MUST be made from a DC current source, like a battery. You CANNOT use AC! All you need to do is run electrical current through a coil of wire. The STRENGTH of the field is determined by the number of coils of turns of wire in the core, and the strength of the DC voltage applied. The DIRECTION of the magnetic field is determined by the DIRECTION of the DC voltage + or -. Now, but applying more or less voltage to the coil, you can “tune” the electromagnet as need to focus the field, and by changing the polarity, you can ‘tune” the field to push or pull the OTHER field that you want to focus. Usually, you will need TWO electromagnets magnets, one on each side of the field, working opposite each other – one PULLS whiel the other PUSHES. You will also nee a pair on the side – left and right.

Any ferromagnetic material, like iron, cobalt, nickel or neodymium.
The strains may ultimately element back outwards, because they repel eachother, or if the orb replaced into lined thoroughly in magnets with a similar pole dealing with inwards, the magnetic fields may cancel one yet another out by the point they could get to the middle.
