Zero gravity can't really be created in an earth-based lab. The closest you can come without going into space is the micro-gravity you get from an airplane that does a series of climbs and dives (often referred to as a "vomit comet"). During the dive portion of the flight, the plane is essentially in freefall and some very short weightless experiments can be conducted.

You can't really "create it" in a lab. You can only couteract the pull with a contraption that works with hydrolics and wires.
In a plane you can do a dive that counters the gravity force for a few minutes.
Einstein said if you got into an elevator that pushed downwards faster than the pull of gravity (say 9 feet per second) and dropped a brick just as the car began to move the brick would slow, stop and fall upwards because it's momentum started in normal gravity and it fallst at just under 8 feet per second, while your feet are on the floor of the elevator and you normalize after a few seconds.

How zero gravity created on earth (Lab)?

It cannot be created, just simulated. Astronauts, for example, dive in a tank full of water and perform their tasks using a model of the real probe, spaceship or whatever they want to fix in space and then they are sent off to space to do the real thing. You can also simulate zero gravity inside a plane which is free falling. Russians have a plane for that task.

You can't. Unless the 'lab' is free falling or diving aircraft in which you won't be pulled against static object and feel 0 gravity.

there is a plane that climbs high and then dives at steep angles to simulate 0 G, but since you said LAB, im not sure...
I think they also use strong magnetic feilds... I have seen a video where they use strong magnetic feilds to levitate a spider...

No way in lab I think

you can create zero g with a plane that makes a steep dive. or with a very very powerful and big electromagnet
