Yoke current & gauss needed

[va-vid]

I am building some 25 inch "prepared TVs" for an art project. Can anyone tell me what typical RMS or peak current is found in the yoke coils, or in the alternative, what typical magnetic field in gauss is developed?

I can of course take any units and convert to my needs. I just need a ball park to do my calculations. I was surprised to not find this information on the web when I specifically searched for it.
