Why there is an induced current in a coil when the bar magnet is thurst into the coil?
This is called ELECTROMAGNETIC INDUCTION.
The electrons have a magnetic field; the magnetic fields of electron and bar magnet interact. Both the bar magnet and the electrons are "pushed". The electrons are lighter; they move more easily. Moving electrons are called a current.
What else can I help you with?
Why is it more difficuilt to move a magnet into a coil of more loops that is connected to a resistor?
Moving a magnet into a coil with more loops induces a stronger magnetic field, which in turn generates a larger induced current in the coil due to Faraday's law of electromagnetic induction. This induced current creates a magnetic field that opposes the motion of the magnet, resulting in increased resistance to movement. The resistor connected to the coil dissipates this induced current as heat, further impeding the magnet's motion.
In which case will electric current be induced in a coil of wire?
An electric current will be induced in a coil of wire when there is a change in magnetic field passing through the coil, according to Faraday's law of electromagnetic induction. This can occur when the magnetic field is moving relative to the coil or when there is a change in the strength of the magnetic field.
Why there is an induced current in a coil when a bar magnet is thrust into the coil?
photons are trapped in the magnetic field when the photon hits the electron of the copper coil the photon take the spot of the electron , its free to move.Answer2: The induced current is a consequence of the conservation of the magnetic field.AnswerCurrent isn't induced into a coil -it's voltagethat is induced. Any current flows as a consequence of this induced voltage only if there is a load connected to the coil.
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What would happen to the voltage and the magnet is withdrawn from the coil?
When the magnet is withdrawn from the coil, the magnetic field within the coil will decrease, inducing a voltage in the coil. This induced voltage will create a current in the coil that flows in such a way as to try to maintain the original magnetic field.
What happen in coil of wire when you pass a magnet through it?
A current would be induced in the coil.

What will happen to the current if the magnet and coil were not moving?
If the magnet and coil are not moving relative to each other, there will be no induced current in the coil. The movement of the magnetic field relative to the coil is required to induce an electromotive force and generate current through 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 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.
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 are two ways to cause a current in a wire coil?
Different ways to induce current in a coil are as given below:(1) If a magnetic field is changed round a coil then an induced current is set up in the coil. It can be done by taking a bar magnet and bringing it closer to the coil or taking it away from the coil.(2) If a coil is moved in a magnetic field, then again an induced current is set up in the coil.(3) If a coil is rotated in a uniform magnetic field, it may also cause an induced current in the coil.(4) If we take two coils and insert them over a non conducting cylindrical roll then on changing current flowing in one coil, an induced current is obtained in the other coil.CommentYou don't induce a 'current' into a coil; you induce a voltage. If that coil is open circuited, then no current will flow. If, on the other hand, the coil is connected to a load, or its opposite ends short-circuited, then the induced voltage will cause a current to flow. Remember, current will only flow if there is a load, or short circuit, and the value of the current will depend upon the value of the induced voltage and the resistance of the load or short circuit.
What are the reasons why a current is induced in a coil?
Current is not induced into a coil. It's voltage that is induced into a coil. If the coil is connected to a load, or even short circuited, then a current will flow as a result of the induced voltage -but it's the voltage, not the resulting current, that's induced!Voltage is induced into a coil because the the changing magnetic field, due to the change in current (0 to Imax or vice versa) applied to that coil. The process is called 'self induction'.
What would happen to the voltage and the magnet is withdrawn from the coil?
When the magnet is withdrawn from the coil, the magnetic field within the coil will decrease, inducing a voltage in the coil. This induced voltage will create a current in the coil that flows in such a way as to try to maintain the original magnetic field.
