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.
Move towards the U magnet so that the poles attach.
A solenoid typically produces a magnetic field similar to that of a bar magnet. The magnetic field lines form loops around the solenoid, making it closely resemble a bar magnet with north and south poles at either end.
Each piece would become a separate magnet with its own two poles, just like the original bar magnet. Cutting a bar magnet does not eliminate its magnetic properties; each piece will still have a north and south pole.
If a bar magnet is suspended vertically, it will align itself in the north-south direction due to Earth's magnetic field. The north pole of the magnet will point towards the geographic north and the south pole towards the geographic south.
Six. Every bar magnet has 2 poles. If a bar magnet is broken, each resultant piece will be a bar magnet in its own right.
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.
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.
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.
A coil of wire carrying a current generates a magnetic field, similar to a bar magnet. Both have north and south poles, with the direction of the magnetic field lines determined by the direction of the current flow in the wire or the orientation of the bar magnet's poles.
An alternating current.
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.
electric current in a solenoid coil
A solenoid magnet, which is a long coil of wire wrapped around a ferromagnetic core, has a similar magnetic field to that of a bar magnet. This is because the magnetic field created by the current flowing through the wire generates a magnetic field similar to that of a bar magnet.
The bar magnet and the electromagnet act identical. The difference being a electromagnet is a coil of wire that has a power source connect to both ends, this energizes the coil with an electromagnetic field.
Move towards the U magnet so that the poles attach.
Well, Many things can produce electricity. An easy way to produce electricity is to get a coil and pass a bar magnet through it.
It requires a current through a coil of wires.
