the coil may destroy itself due to the magnetic repulsion forces created inside the coil by the current
Actually, it's the opposite. The windings attract each other, because the current in adjacent windings is flowing in the same direction.

But what about all the parallel magnetic field lines running in the same direction down the center of the coil? Won't they cause an outward (radial) force on the windings, tending to increase the diameter of the coil?
I'm not an EE--what am I doing here?

You're right, completely forgot about that. ;D
<fellbuendel> it's arduino, you're not supposed to know anything about what you're doing
<fellbuendel> if you knew, you wouldn't be using it

You're both right: the coil compresses axially and expands radially. :)
