Depends entirely on how fast you want the MOSFET to switch.a quick search shows that one bjt npn transistor probably is enough to drive an n channel mosfet
Look at the circuit schematic for a class AB audio amplifier. It will actively pull the gate of a MOSFET up and down. Here is an example:I cant seem to make something that i can use for a tesla coil,and i just want to make my own driver
Yep. No need to worry about that pesky crossover distortion in a switch.You never said the frequency the Tesla coil driver operates at. A Mosfet has a high gate capacitance that takes a fairly high current for it to charge and discharge quickly. Quickly means fast.
Here is a Mosfet driver circuit that turns the Mosfet on and off quickly with a pair of transistors:
