I'm sure you mean the magnetic field
No. Magnetic compasses work based on the Earth's mantic field, in space there is no magnetic field for the compasses to work with. A different system, possibly similar to Global Positioning System (GPS) might work, call it the Universal Positioning System. On certain rocky planets it could work, but some planets don't have a magnetic field, like Mars. So a traditional magnetic compass wouldn't work in space, or at least it won't get you where you want to go.
atnosphere gets held back by earths gravtional field
Earth's magnetic field (and the surface magnetic field) is approximately a magnetic dipole, with the magnetic field South pole near the Earth's geographic north pole (see Magnetic North Pole) and the other magnetic field N pole near the Earth's geographic south pole (see Magnetic South Pole). This makes the compass usable for navigation. The cause of the field can be explained by dynamo theory. A magnetic field extends infinitely, though it weakens with distance from its source. The Earth's magnetic field, also called the geomagnetic field, which effectively extends several tens of thousands of kilometres into space, forms the Earth's magnetosphere. A paleomagnetic study of Australian red dacite and pillow basalt has estimated the magnetic field to be at least 3.5 billion years old.
I'm sure you mean the magnetic field
As far as the electric field is stationary then no magnetic field. But when electric field is moving at a uniform speed then a magnetic field will be produced. This is what we call Lorentz magnetic field.
I believe you are looking for magnetic field. Although it is not exactly space.
It is Earths' "Magnetosphere".

Flux means the rate of change of magnetic field lines through a particular region in space. Magnetic field lines are imaginary lines drawn to demonstrate the magnetic field through a region in space. No flux condition means the magnetic field lines in the observed region in space is uniform throughout the experiment.
Earth's magnetic field can make magnets out of ferromagnetic material and it affects the movements of electrically charged particles in space.

Faraday's Law
Scientists follow the magnetic field lines of the earth and measure them regularly. They will compare the earlier measurements and note the changes in position of the magnetic axis and decide if it is changing or not! Also if there are sudden changes observed in magnetic field lines bec of solar flares from sun. Magnetism is an interesting chapter! learn more by watching and subscribing to this space @PhysicsFusion-sm3tr Hope this helps
If the magnetic field is caused only by a current, you can turn the current off.If you have another magnetic field, for example due to a permanent magnet, with a current you can create a magnetic field that counters the first one. But that will only work in certain regions in space; you can't cancel such a magnetic field everywhere in space.
