@Agentgates. Spray paint your acrylic tubes or cover in paper or duct tape etc.

Try the local home improvement store and look at the concrete form tubes. They come in sizes that range from roughly 6~7' and up. and they are a bit thicker in the side walls. Just an idea...

CD or DVD cases are roughly 5" (125mm) dia. Might work well.

Tony,
I don't  know if you believe in a higher power in this world?
But I do.
All I can do at this point is pray.

I am

Chet

Oh, ok I misunderstood. Yes I do. And thanks for the prayer.

@Everybody

I am ready with the coil and stop here with the experimenting and moving to design a complete driving circuitry with ordinary devices, variable duty cycle on each channel. I'll test it in simulator, build it on the breadboard and test it in reality as well by driving the coils and come back with the results.

@Tony,

          Take great care with simulator, it can show you what you want but not necessary the true reality. Alot of people already build some test circuit in a simulator and got Unity, but that was just a error by the simulator who was using a Ideal model for all component in it. Use the real characteristic of your component in your simulation.
