Voltage can never be induced in a straight open wire because flux through a wire is zero but a coil made up of a wire can have induced voltage.
Methods
Move a magnet to and fro through the coil, the magnitude can be changed by altering the relative velocities between them
Move the coil relative to he still magnet
Place the coil in a time varying magnetic field such that the flux linked through the coil changes with respect to time
Place the coil tn an uniform magnetic field and alter its area with respect to time

What happens when a coil of wire cuts through a magnetic field?
If the magnetic field is fluctuating, or the coil of wire and magnetic field are moving with respect to each other, then a current is induced in the coil of wire. If the two are stationary and the magnetic field is stable, then no current is induced in the coil. However, if there is a current in the coil, from another source, then the coil and the field will exhibit a relative force that will tend to move the coil with respect to the field.
Define the term induced current?
a current can be induced by changing the area of a coil in a constant magnetic field. By Faraday's Law: the induced current is proportional to the rate of the change of flux in a loop of wire. With magnetic flux being defined as the product of the magnitude of the magnetic field and the area of the loop. The direction of the current is found from Len's Law: The induced current produces an induced magnetic field that opposes the change of flux causing the current.CommentYou don't induce a current, you induce a voltage. And Faraday's Law states that the induced voltage, not current, is proportional to the rate of change of flux! If the coil is open circuited, a voltage is still induced into the coil but no current will flow. For current to flow, the coil must be connected to a load (or short circuited), and this current is dependent upon the values of the induced voltage and the resistance of the load.
In a three phase four wire wye system having 277V for lighting the three phase motors operate on what voltage?
480 Volt
Can three or four 20awg wire carry the same current as 1 14awgwire?
No. 20 gage wire is only rated for low voltage. I wouldn't do it like that if I were you

For voltage to be induced from one stationary wire to another one wire must have what type of flow?
for uhmm voltage?:)
What is difference between induced voltage and induced current?
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.
What are the three ways in which voltage can be induces in a wire?
Voltage can never be induced in a straight open wire because flux through a wire is zero but a coil made up of a wire can have induced voltage. Methods Move a magnet to and fro through the coil, the magnitude can be changed by altering the relative velocities between them Move the coil relative to he still magnet Place the coil in a time varying magnetic field such that the flux linked through the coil changes with respect to time Place the coil tn an uniform magnetic field and alter its area with respect to time
For voltage to be induced from one stationary wire to another one wire must have a n what type of current flow?
Intermittent. Faraday's law tells us that voltage can only be induced in a second coil when the current in the first coil changes
When a magnetic field and a wire are moved near each other the voltage produced is said to be?
Induced.
How was current produce or induced?
Current can be induced in a conductor through electromagnetic induction, where a changing magnetic field causes a flow of electric current. This can be achieved by moving a magnet near a conductor or by varying the current in one nearby. Alternatively, current can be produced by a voltage source such as a battery or generator that creates a potential difference to drive the flow of electrons.
Why the coil of a transformer donot get short circuited even though it is continuous wire?
If energized from the high side, the induced voltage in the secondary counter acts the current flowing in the primary (or pushes against the flow of current in the primary). This is a fundamental property governing the operation of induction - the induced voltage on a wire from another source will induce a voltage back on the source in the opposite direction of the source's voltage.
How single point grounding reduces ground loop?
A voltage can be induced on a ground wire by other wires nearby. If you have more than one ground wire, The induced voltage will cause a current flow up one, and down through the other. By removing one of the two, you interrupt the loop.
What are two ways to increase the current in a wire?
Increase the voltage applied to the wire. Decrease the resistance of the wire.
What would induce a greater electric current in a wire?
A greater electric current in a wire can be induced by increasing the voltage applied across the wire or decreasing the resistance of the wire. Both factors contribute to Ohm's Law (V=IR), where V is voltage, I is current, and R is resistance. Increasing the voltage or decreasing the resistance will lead to a higher current flowing through the wire.
What is inducing voltage?
Induced voltage happens through induction. When a wire goes through a magnetic field a voltage is induced across its ends. The basic equation is Ampere's law: Curl E = dB/dt at every point, where E is the electric field and B the magnetic flux density. For a loop of wire Stokes's theorem can be applied to this: Integral E.dl = d/dt of the surface integral of B.dS which says that the induced voltage along the loop equals the rate of change of the magnetic flux linking the area of the loop.
Moving a magnet in and out of a coil of wire produces?
Moving a magnet in and out of a coil of wire induces an electric current in the wire. This phenomenon is known as electromagnetic induction and is the basis for how generators produce electricity.
