Two ways to increase the current would be to increase the surface area of the electrodes and make changes to the electrolyte to speed up the movement of the ions (this might involve increasing the concentration of the electolyte or warming it up to speed up diffusion).
There are two ways to elongate a piece of wire: Either stretch it, or attach another piece onto one end of it. Either way, the resistance will increase.
There are two ways of doing this; 1) moving a magnet perpendicular(at right angles) to a coil of wire 2) placing a coil of wire in close proximity to another coil carrying an AC current.

There are no known ways to affect the force of gravity. If the masses increase or the distance between the masses decreases the resultant force will increase (and vice versa).
-- Increase the current (amperes) flowing through the coil of wire that surrounds the electromagnet. -- Increase the number of 'turns' of wire in the coil.
The resistance can be changed in following two ways: 1.By change the length of the wire. 2.By changing the area of cross section of the wire.

More currents, or more loops.
Increase the resistance (ohms) Decrease the voltage (Volts)

The two ways to increase the strength of a magnetic field of an electromagnet include increasing the current and increasing the number of wire revolutions around the iron bar. Having fewer windings weakens the electromagnetic strength.
1) Use an operational amplifier.2) If voltage is not an issue, a transformer may be used.
U can increase and decrease it
1. Increase the strength of the magnetic field. (More field lines to be cut by wire, therefore more voltage induced) 2. Move the magnet - or the wire - more quickly. (More field lines cut per second, therefore more voltage induced) 3. More coils in wire. (A single straight wire moved in a magnetic field will cut the lines once, but a coil of wire will cut the lines twice. More coils, more cutting, more induced voltage).
Any circuit has at least two conductors. Otherwise, by Kirchoff's current law, there would be no current, therefore no power, therefore no work. The current coming on one wire is exactly balanced by the current going out on the other wire. If there is a third wire/connection, such as a ground wire, it is possible for current to flow on that conductor as well but, usually, there is no current expected to flow on the (safety) ground conductor.
