Form the wire into a coil, by wrapping it around and around.
Connect the ends of the coil to the input of a sensitive amplifier. Use a domestic HiFi amplifier by connecting it to the Phono connection.
When you move the magnet near the coil, you will hear a 'Whummp" from the speakers. Attach the magnet to something that vibrates and you will hear a sound, as it vibrates near the coil.
This is how the pick up on an Electric Guitar works, or a simple microphone when attached to a diaphragm that picks up air vibration.
Sound can be induced into a single wire, but the result may be too weak to hear or measure at home.
Experiment by using fewer and fewer turns in your coil, until you end up with just a single straight wire.

What does the combination of a magnetic field and a coiled wire create strong magnet week magnet or neutral magnet?
it creates a very strong magnet A+ users
Magnetism can sometimes be induced in an iron object by?
1.Stroking it with a magnet 2. Applying a current to a coil of wire wrapped around the iron
When a magnet is pushed through a loop of wire what does it produces?
When the magnetic flux (field) intersecting a loop of wire changes, a voltage is induced between the ends of the loop. If a resistor is connected between the ends, a current flows and power is produced, but in this case a force is needed to move the magnet, and this provides the power.
How can magnet produce current?
Faraday found that a wire passed by a magnet induces a current in the wire. This led to making an electrical generator.
What will be attracted to ( or repelled by) a magnet?
a copper wire carrying current and another magnet.
What happen in coil of wire when you pass a magnet through it?
A current would be induced in the coil.
In which case will electric current be induced in a coil of wire?
The coil must experience a changing magnetic field in order to have a current induced. You can rotate the coil between the poles of a magnet, or rotate the magnet around the coil.
Moving a magnet in and out of a coil of wire produces?
That will induce a voltage across the wire.
A loop of wire is placed within a magnetic field If the loop of wire is stationary as is the magnetic field will a current be induced in the wire?
No it will not. In order to get electrical activity you need motion. Either the magnet or the wire must move.
What would be the direction of the induced current if the s-pole of a bar magnet were quickly withdrawn from it?
That depends on the direction in which the coil of wire is wound.
What does the combination of a magnetic field and a coiled wire create strong magnet week magnet or neutral magnet?
it creates a very strong magnet A+ users
What are the three ways in which voltage can be induced 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
What happens to a magnet when copper rubs aganist it?
It might leave a copper coloured streak across the magnet, but apart from that, nothing much. I think you are looking at what happens to a copper wire when it is moved in a magnetic field. In which case the answer is, a current is induced in the wire. (It does not have to touch)
Magnetism can sometimes be induced in an iron object by?
1.Stroking it with a magnet 2. Applying a current to a coil of wire wrapped around the iron
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 happens when a magnet is moved towards a coil?
You will generate electricity. As the wire cuts through the magnetic field.As the magnet is moved, there will be an induced electro-motive force (EMF) which can cause a current in the coil. Once the magnet stops moving, the current will go to zero.
What happens to the amount of voltage induced by pushing a magnet through loops of wire if the number of loops is doubled?
Also doubled.
