A magnet inside a wire loop can produce a current?
Only while the magnet is entering or leaving the loop. If you hold it still, no current is generated. The same goes for a longer magnet where the loop is being moved, but the magnet always remains inside the loop; no current.
Do a Vacuum cleaner needs a magnet?
If the vacuum cleaner is powered by electricity this is used to turn the electric motor which is needed to create the suction or vacuum. That motor either has permanent magnets inside it, or the current passes through many "turns" of wire to create magnets when you switch the cleaner on. Early experiment in electricity showed that if a wire is moved in a magnetic field some current is created. Similarly, if a magnet is moved near to a wire the same result occurs. So, yes the cleaner does need a magnet.
Do power stations work with a wire and magnet?
Some power stations do work with a wire and magnet but some others don't.
Describe the energy transformation that takes place in a generator?
Mechanical energy to electrical energy. A generator consists of a large magnet placed inside a coil of wire. . When the magnet is rotated (mechanical) it impels the electrons in the wire to move(electrical). Conversely, with suitable electrical engineering, when a magnet is placed inside a wire coil and electricity is passed through the wire, it will make the magnet rotate.
How to make a temporary magnet?
First, you get a long wire (12 inches). Then, you get a nail and wrap the wire around the nail, but leave at least 1 inch of wire on each side. The use the ends of the wire and put it on the big magnet and it will pick up magnetic things.
What happens when a magnet is moved alongside a wire?
the electrons in the wire begin to flow
When a magnet is moved alongside a wire what happens?
the electrons in the wire begin to flow
When a magnet is alongside a wire what happens?
the electrons in the wire begin to flow
When a magnet is moved through a coil of wire an electric current is generated in the coil because?
the magnetic field affecting the wire changes as the magnet moves.
What would be produced if you moved a bar magnet in and out of the wire coil?
An alternating current.
What is generated when a permanent magnet is moved in front of a coiled wire and the magnet's magnetic field pushes and pulls electrons in the coiled wire?
an AC, or alternating current
True or false when a magnet is moved electricity is formed?
1/2 true, when moved though a wire coil electricity is formed.
A horseshoe magnet is moved back and forth across a piece of copper wire an electric current is detectable in the wire?
yes, it will be very small but the inductance from the magnet should stimulate a current in the wire as it will cause electrons to move.
What does copper wire and magnets have to do with Electricity?
a magnet moved through a copper coil makes electricity
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.
A magnet can generate an electric current in a wire if the magnet is close enough to the wire and if the magnet is also?
strong
A magnet inside a wire loop can produce a current?
Only while the magnet is entering or leaving the loop. If you hold it still, no current is generated. The same goes for a longer magnet where the loop is being moved, but the magnet always remains inside the loop; no current.
