Moving a magnet alongside a wire induces an electric current in the wire due to electromagnetic induction. This phenomenon demonstrates the interconversion of magnetic and electrical energy. The current produced is proportional to the rate of change of the magnetic field, as described by Faraday's law of electromagnetic induction.

Will a magnet pick up more nails when covered in copper wire or metal wire?
The magnet will pick up more nails when covered in metal wire rather than copper wire. Copper is not a magnetic material, so the nails will not be attracted to the magnet when covered in copper wire. Metal wire, on the other hand, can still allow the magnetic force to attract the nails.
What happens to a nichrome wire when a current flows through it?
When a current flows through a nichrome wire, the wire heats up due to resistance. This increase in temperature causes the wire to glow and emit heat, which is why nichrome wire is often used in heating elements and appliances.
What happens to the matter in copper wire when heated?
When copper wire is heated, the atoms within the wire vibrate more vigorously, leading to an increase in kinetic energy. This causes the wire to expand slightly in length and thickness. If heated excessively, the wire can eventually melt and transform into a liquid state.
What happens to a nichrome wire in a non-luminous flame?
A nichrome wire will not burn or react in a non-luminous flame as it is a highly stable and heat-resistant material. It will retain its structure and properties without undergoing any significant changes.
What happens to copper wire when heated?
When copper wire is heated, it expands due to thermal expansion. As it gets hotter, the electrons in the copper atoms move more freely, increasing electrical resistance. Excessive heating can cause the copper wire to melt and ultimately vaporize.
What happens when a magnet is moved alongside a wire?
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 alongside a wire what happenes?
the electrons in the wire begin to flow
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)
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 when moving a magnet through a coil of wire?
When a magnet is moved through a coil of wire, it induces an electric current in the wire due to electromagnetic induction. This occurs because the changing magnetic field created by the moving magnet interacts with the electrons in the wire, causing them to move and generate an electric current. This phenomenon is the basis for generating electricity in devices such as generators and motors.
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
What happens to copper wire because of the moving magnet?
The copper wire carries an electric current.
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
True or false when a magnet is moved electricity is formed?
True. When a magnet is moved near a conductor, such as a wire, it causes a change in the magnetic field around the conductor. This change induces an electric current to flow in the conductor, resulting in the formation of electricity.
