the relationship between the deflection of the wire and the ccurrent is when the voltage is 12volt the current become higher.
Another Answer
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 relationship between current and length of a wire is inversely proportional when the resistance of the wire remains constant. This means that as the length of the wire increases, the current flowing through it decreases, and vice versa. This relationship is described by Ohm's Law, where resistance (R) is directly proportional to length (L) and inversely proportional to current (I).
When a current-carrying wire is placed in a magnetic field, a force is exerted on the wire due to the interaction between the magnetic field and the electric current. This force causes the wire to move or experience a deflection, depending on the orientation of the wire and the magnetic field.
The relationship between the magnetic field and current in a conducting wire is described by Ampre's law, which states that a current flowing through a wire creates a magnetic field around it. The strength of the magnetic field is directly proportional to the current flowing through the wire.
A compass needle placed near a current-carrying wire shows deflection because the moving charges in the wire create a magnetic field around the wire. This magnetic field interacts with the magnetic field of the compass needle, causing it to align with the direction of the current flow in the wire.
The relationship between the current flowing through a wire and the potential difference across it is described by Ohm's Law. Ohm's Law states that the current (I) flowing through a wire is directly proportional to the potential difference (V) across it, and inversely proportional to the resistance (R) of the wire. Mathematically, this relationship is represented as V I R.
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.)

current flowing throgh a conducter or wire it emmits a circuler magnetic field around the wire.a compass react to a magnetic field by point to the north pole.(point throgh the south to the north).
The inductance of a wire is directly related to the amount of current it can carry. Higher inductance in a wire can limit the amount of current it can carry, as it resists changes in current flow. This can lead to increased voltage drops and power losses in the wire.
When an electric current flows through a wire, it creates a magnetic field around the wire. If this wire is placed in the presence of another magnetic field, the two fields can interact, causing the wire to deflect. This phenomenon is known as the magnetic deflection of an electric current.
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.
