Like everywhere else on the surface of the Earth, the force of gravity is 9.8 Nkg-1.
The astronauts on the Shuttle lift-off experience a gravitational-pull "G-Force" of not more than 3-g's (acceleration 29.4 m/s²) but astronauts train for up to 6-g's.
gravity and lift
You have to overcome the force of gravity. So, if you're in the space shuttle which weighs 240,000 pounds at liftoff, you have to have enough force to overcome that weight.
During the liftoff of a rocket, the two main forces present are thrust and gravity. Thrust is the force generated by the rocket engines pushing against the ground, propelling the rocket upwards, while gravity acts in the opposite direction, pulling the rocket downwards.

gravity and lift
During liftoff, the two main forces acting on a rocket are thrust and gravity. Thrust is generated by the rocket's engines, pushing it upward, while gravity pulls the rocket back towards the Earth. These forces must be balanced for the rocket to achieve liftoff and ascend into space.
You can find various estimates for this because the number is not certain. The number I got from NASA's data is about 0.89 times the Earth's gravity.
Yes, magnets would still work in the absence of gravity. The force generated by magnets, known as the magnetic force, would still attract or repel objects based on their polarity, regardless of the presence of gravity.

what is the force of gravity on mecury
Gravity is a force but has no mass.
gravity not as a force, but as the curvature of spacetime
