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 else can I help you with?
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
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.
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 will be attracted to ( or repelled by) a magnet?
a copper wire carrying current and another magnet.
What happens when a magnet is moved alongside a wire?
the electrons in the wire begin to flow
What happen in coil of wire when you pass a magnet through it?
A current would be induced in the coil.
What happens when a magnet moves in a coil wire?
When a magnet moves in a coil of wire, it induces an electric current in the wire through electromagnetic induction. This phenomenon is described by Faraday's law of electromagnetic induction. The induced current flows in the wire in response to the changing magnetic field produced by the moving magnet.
How do you produce electricity using a magnet and a wire coil?
By moving a magnet through a wire coil, an electric current is induced in the wire due to electromagnetic induction. This current is generated as a result of the changing magnetic field produced by the moving magnet cutting across the wire coil. This process converts mechanical energy (movement of the magnet) into electrical energy (current in the wire).
What energy is produced when a coiled wire is spun around a magnet?
When a coiled wire is spun around a magnet, electrical energy is induced in the wire through electromagnetic induction. This process is the principle behind how generators and dynamos create electricity.
How can a magnet induce current in a wire?
When a magnet moves near a wire, it creates a changing magnetic field around the wire. This changing magnetic field induces an electric current to flow in the wire through electromagnetic induction. The current is only induced while there is a relative motion between the magnet and the wire, or if the magnetic field intensity changes.
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.
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.
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 will happen if a bar magnet is moved through a coil of wire?
Moving a bar magnet through a coil of wire induces an electromotive force (EMF) in the coil. This phenomenon is known as electromagnetic induction, according to Faraday's law. The induced current in the wire will produce a magnetic field that opposes the motion of the magnet, following Lenz's law.
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)
