the relationship between the deflection of the wire and the ccurrent is when the voltage is 12volt the current become higher.

Presumably you are referring to the force on a conductor placed in a magnetic field? In which case, it is equal to the Flux Density of the field (in teslas), the length of the conductor within the field (in metres), and the value of the current passing through the conductor (in amperes).
If the resistance of the wire is 30 ohms and the voltage between the two ends of the wire is 45 volts,then the current through the wire isI = E/R = (45/30) = 1.5 amperes.
Just as a current flowing through a wire will produce a magnetic field, so a wire moving through a magnetic field will have a current flowing through it. This is called electromagnetic induction and the current in the wire is called induced current. A stationary wire in the presence of a changing magnetic field also has an induced current. A changing magnetic field can be produced either by moving a magnet near to the stationary wire or by using alternating current. A stationary wire in a magnetic field which is not changing will have no current induced in it. You will sometimes see this effect described as induced voltage. Strictly speaking, you will only get an induced current in the wire if it is part of a complete circuit. A wire which is unconnected at both ends will have a difference in voltage between the ends (a potential difference) but current can only flow when the wire is in a circuit. Induced current is used in electricity generation and transformers.Another AnswerThere is no such thing as an 'induced current', only an 'induced voltage'. Current will flow only if the conductor into which the voltage is induced forms part of a closed circuit.

An electro magnet is created when a current is passed through a coil of wire. This effect is the main operation of how an electrical solenoid operates.
if you know the gauge of the wire you can learn its current carrying capacity

The thicker the wire, the higher the current the wire is capable of passing. This is due to two things: 1.) the larger wire has less resistance, and 2.) the larger wire has more surface area to dissipate power.
The compass needle will turn until it's perpendicular to the wire, provided the current in the wire is enough to generate a magnetic field around the wire that's strong enough to swamp out the effects of the Earth's magnetic field. (That doesn't take much current.)
The wire resistance is proportional to the length of wire divided by its cross-section area. The voltage drop is proportional to the resistance times the current.
There is none. There is a relationship between voltage and current and turns ratios in a transformer. But this rule remains - power in = power out. You don't get anything for free.
The relationship is that as the current passing through the wire increases so does the heating effect in the wire. To see its effect just use the formula: W=I2R R is resistance in ohms I is current in amps W is the heat output in watts Hope this helps

The frequency has no direct relationship to the size of wire. Wire is sized as to the amount of current a load draws in a circuit.
The higher the current, the more heat generated. Also, the smaller the diameter of the wire, the higher the heat. It is important to choose the correct amperage rating of the wire to prevent fires.Another AnswerThe work done by an electric current is the product of the square of that current, and the resistance of the conductor. The resulting heat depends upon the difference between the temperature of the conductor and that of the surrounding air. Remember, heat is defined as the transfer of energy between objects at different temperatures.

Because there is no potential difference (voltage) between your hands. You can observe that easily if you have a voltmeter: Hold one probe in each hand, and read the voltage between your hands. The current in the wire is (voltage between the ends of the wire) divided by (resistance of the wire). If voltage=0, then current=0.
