What will happen to the current if the magnet and coil were not moving?

I assume you mean in a setup similar to an electrical generator. Here, current is ONLY produced if there is relative movement, between the magnet and coil. Without movement, there will be no current.

When there is a change in the magnetic field in a closed loop of wire?
This can be done by moving a magnet through a coil of wire. This is called electromagnetic induction and it results in a voltage being induced in the coil. The charges in the coil are set in motion...
Can a magnet cause an electric current to flow through a wire?
You obviously cannot more a magnet through a coil in the direction of the current, because the magnet must move, axially, along the length of the coil, while the current moves radially, around the coil. However, if you move a conductor within a coil carrying a d.c. current, then the magnet will induce a voltage into that coil which will oppose the voltage applied to the coil.
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 happens when a bar magnet is thrust into a coil?
When a bar magnet is thrust into a coil, the magnetic field of the magnet will "sweep" across the wire in the coil and induce a voltage in that coil. This is called induction, and if the coil is connected to an external circuit, there will be current flow in that circuit.
What shape of a permanent magnet corresponds to the magnetic field formed by a solenoid?
The magnetic field produced by electric current in a solenoid coil is similar to that of a bar magnet.
Generating and inducing an electric current can be done through?
a moving coil and moving magnet
What happen in coil of wire when you pass a magnet through it?
A current would be induced in the coil.
What is the purpose of the permanent magnet in the moving coil meter?
The purpose of the permanent magnet in the moving coil meter is to measure electrical current. The coil will have a magnetic field which will react to the magnetic field of the permanent magnet. Since opposite poles attract, it will cause for the coil to move.Ê
What can electricity be created by?
An electric current can be created by moving a magnet through a metal coil.
Will Dragging a magnet through a wire coil will create electricity?
Yes. That peculiar action weill create a current in the coil for as long as you keep the magnet moving.
If a magnet is held close to a coil of wire will it cause current to flow?
Yes, but only if the magnet or the wire are kept moving.
Producing an electric current by moving a bar magnet in and out of a coil of wire is called?
Electromagnetic induction.
Why there is an induced current in a coil when a bar magnet is thrust out of the coil?
The magnetic lines of force surrounding the bar magnet, cut through the coils of wire, causing electrons to move. This induces an electric current. It is the movement that is important, whether moving into, or out of, the coil.
What happens when a magnet is pushed into the coil during an experiment to demonstrate electromagnetic induction?
-- While the magnet is moving, there is a voltage between the ends of the coil and, if there's any connection between the ends, then there's a current in the coil. -- When the magnet stops moving, all of that goes away. -- When the magnet is pulled out, it all happens again, but with the opposite polarity.
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 is most likely to happen if you where to place a magnet in a coil of current carrying wire?
It would spin.
Why do speaker have magnet?
The magnet is part of the 'motor' of the sub. The coil inside the magnet has alternating current running through it. The coil acts as an electromagnet and pulls itself up or pushes itself down moving the cone of the speaker. The bigger the magnet, the stronger the magnetic field inside the speaker where the coil is.
