ELECTRIC  BALL

• The electric ball or plasma globe was invented in 1864 by Nikola Tesla.
 

It's usually a clear glass sphere filled with a mixture of various noble gases with a high-voltage electrode in the center of the sphere.

This gases are: neon, argon, xenon and krypton.

The energy of the ball, comes from a lower-voltage power supply usually connected to mains power, and flows through a high-voltage transformer combined with a high-frequency electronic oscillator.

The circuit inside the electrode can be considered as a specialized power inverter.

An electrical current is produced within any conductive object near the ball. The glass acts like a dielectric in a capacitor formed between the ionized gas and the hand.

However, the plasma ball stills emits a very high dose of electromagnetic force. Therefore,we use the plasma ball as a EMF emitter.
