controllable as in a pendulum?... a geostationary orbit?... using it to slingshot probes to get them to travel at 65000k/hr?... using it to generate electricity (hydro-electric power from dams)?...
erm id say yes to this one, if its a force it can be manipulated to our advantage.

Ever since electricity was tamed in the 19th century, the idea of manipulating gravity by altering an electromagnetic field has been the subject of intriguing experiments and occasional bursts of irrational exuberance. Physicists insist that because gravity is a basic force of nature, constructing an antigravity machine is theoretically impossible. But recently, and not without some reluctance, they have begun to consider another possibility. Several highly respected physicists say it might be possible to construct a force-field machine that acts on all matter in a way that is similar to gravity. Strictly speaking, it wouldn't be an antigravity machine. But by exerting an attractive or repulsive force on all matter, it would be the functional equivalent of the impossible machine.

Not really. The problem is that gravity is much, much weaker than magnetism. It just takes way too much mass to get any decent force from gravity alone. In contrast, readily made currents are enough to give large magnetic fields.

yes it can be. magnetism and electricity are linked intrinsically.
Using an electrical source, one can create an electromagnet.
Simple example.
Get a nail(make sure its not aluminum).
wrap some copper wire(6 AWG gauge) around the nail about 50-75 times.
make sure the wire is "stripped" of its plastic coating.
now attach each end of the wire to a heavy duty 6 volt battery.
now pass the nail over some paper clips;they will be picked up.
now disconnect the battery. the paper clips drop.
magnetism controllable yes.

No. Mainly because, unlike the magnetism, gravity is lone.

Yes...it is
We can control gravity... if we can control mass...
Because gravity is equal to mass.
And to control mass.. we need to control energy (einstein law)

I wouldn't really say "controllable" is the right word. Manipulatable would be more accurate...in which case, YES.
Either way, you can't get past laws of physics.

No,because it is natural

Of course! All one has to do is shave off mass.

yes it is controllable
