1) Put more current through the magnet. You will need a higher voltage power supply to do this.
2) More loops of wire. This one is a bit tricky since the increased length also increases the resistance, so if you can't keep it compact enough this won't help very much.
3) An iron core. Wrap your wire around a piece of iron. Not all iron is equally susceptible to magnetic fields, so experimenting will definitely help here. The ideal iron would be the kind they use in transformers, but that's typically annular which is not ideal for producing exterior magnetic fields.
Other methods would involve examining the exact geometry of your windings, which I doubt you want to do.

Magnetic field lines never intersect each other because
There will be two directions of the field at the same point.
Feild lines repel each other
Field lines follow discrete paths only
If field lines intersect they create a new magnetic field within the existing fieldTwo parallel wires carry currents of 20 A and 40 A in opposite directions. Another wire carrying a current antiparallel to 20 A is placed midway between the two wires. The magnetic force on it will be
