What The distance that the pointer of a galvanometer moves depends on the amount of magnetism in the loops of the armature?
The distance that the pointer of a galvanometer moves is determined by the strength of the magnetic field present in the coils or loops of the armature. When an electric current flows through the coils, it interacts with the magnetic field produced by the coils, resulting in a deflection of the pointer. The greater the magnetism in the loops, the larger the deflection of the pointer.

Is gravity a magnetic force?
No. Magnetism and gravity are quite different forces. For starters, gravity acts on all masses, and the amount of force depends only on the masses and the distance - and it is always attractive. The magnetic force depends on the material, and it can be both attractive and repulsive, depending on the orientation.No. Magnetism and gravity are quite different forces.

What are the factors on which the figure of merit of galvanometer depends?
The figure of merit of a galvanometer depends on its sensitivity, which is the amount of deflection for a given current; its damping, which is how quickly the needle returns to zero position after being deflected; and its resistance, which affects the amount of current needed for deflection.
What happen to voltage sensitivity if current sensitivity is increase of agalvanometer?
If current sensitivity of a galvanometer is increased, the voltage sensitivity remains the same. Voltage sensitivity depends on the resistance of the galvanometer coil, while current sensitivity depends on the number of turns in the coil. Therefore, changing current sensitivity does not affect voltage sensitivity.
What is the pulling or pushing force from a magnet?
The force that binds us is not very static. It's something transcending electromagnetic. (From one of my favorite love sonnets). Is the force what? There are four fundamental forces: Strong nuclear, weak nuclear, electromagnetism (light, radio, heat, magnetism, etc.), and the weakest of the four: gravity.
The image produced by a convex lens depends on what?
The image depends on the distance the object is from the lens.

Is galvanometer generator alternating current or direct current needed to operate an electric motor?
That depends if it is an ac or dc motor.
What is inductor alternator?
The armature and the field windings of an inductor alternator are both accommodated in the stator. The three phase ac armature windings are distributed in small slots and the dc field windings are concentrated in two slots in the stator. Each field coil spans half the total number of stator slots. Armature coils are connected in star and field coils are connected in series. The rotor resembles a cogged wheel, with no winding. The core of the stator, which is completely embraced by the field coils, will retain a residual magnetism if excited once. When the rotor is rotated, the passage of the rotor teeth alternatively under the field offers a varying reluctance path for the flux produced by the field coils. This flux, which varies periodically, links with the armature coils and induces an emf in them. The frequency of the induced emf depends on the speed of the rotor. The magnitude depends on the speed of the rotor as well as on the level of excitation. The armature and the field windings of an inductor alternator are both accommodated in the stator.

Magnetism depends on the arrangement of what?
Magnetism depends on the arrangement of atoms within a material. When atoms are aligned in the same direction, they create a magnetic field. The alignment of these magnetic moments determines the material's magnetic properties.
What value of resistance is used to convert galvanometer into voltmeter?
It depends on the resistance of the galvanometer and its full scale current. A 100 ohm meter reading 1 milliampere would require 0.1 volts to reach full scale, so it would require about 0.1 ohms in parallel to become a 1 ampere ammeter.
What happen to voltage sensitivity if current sensitivity is increase of agalvanometer?
If current sensitivity of a galvanometer is increased, the voltage sensitivity remains the same. Voltage sensitivity depends on the resistance of the galvanometer coil, while current sensitivity depends on the number of turns in the coil. Therefore, changing current sensitivity does not affect voltage sensitivity.
What resistance value is add to convert a galvanometer into a voltmeter?
It depends on the resistance of the galvanometer and the current required to reach full scale. A 100 ohm meter requiring 1 milliampere would require 99.9 KOhms in series to become a 100 volt voltmeter.
Does gravitational force is like megnetic force due to megma rotates inside earth?
No. The gravitational force is a different force from magnetism, and depends only on the mass and the distance. Specifically, a body does not need to rotate to have gravitational force.
If you were to mechanically rotate the armature in an electric motor what would happen?
You said "armature" so it is a dc motor. Hence if the field is permanent magnet type then a voltage appears at the armature terminals nd its magnitude depends on the speed nd magnetic field strength. If it's field coils, then they must be seperately excited (if it don't possess residual). By changing the field strength you can vary the voltage produced at armature terminals.
How many kw can a 12 volt motor generate?
It depends on the current rating of the armature winding, which will determine its input power. It's output power then depends on the motor's efficiency.
What is residual magnetisim?
It depends on the context in which you are referring to it, but basically Residual Magnetism is that magnetism remaining in the core of an electromagnet after the coil current is removed. In the widest use of the term, it could be used to refer to that magnetism left in a magnetically susceptible substance when it cools past its Curie point, (paleomagnetism is an example of this).
