(OP)
some say that when a high frequency source gets near to a flourescent lamp it makes the lamp work ,so is it true and if so what is the principle ? magnetic field or electric field or frequency?

While dry air has a breakdown voltage of around 3x10^6 V/meter, the breakdown voltage needed to strike an arc in a fluorescent lamp is on the order of a few hundred volts per meter.

A friend built a Tesla coil and would light a 30W tube by holding it near the coil.
