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.

∙ 15y agoThe bar magnet would slowly sink as if it were normal wire. Lenz's law states that the magnet's motion will create small amounts of electrical current in the wire. A high resistence wire vs. a low resistence wire would be a very small change because the electrical current will still exist. The bar magnet would simply sink at a slower rate.

∙ 11y agowhen the bar magnet is moved repeatedly in and out of the wire coil then
according to faraday's law of electromagnetic induction there is produce a change in magnetic flux hence a emf is induced called induced emf.

when a coil of wire and a bar magnet are moved in relation to each other, an electric
is produced. This current is produced because the strength of the field at the location
of the coil changes

What happens to the bar magnet as it nears the U magnet the bar magnet will?
Move towards the U magnet so that the poles attach.
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.
What happens if a bar magnet is suspended vertically?
the bar magnet will become stable whereever it is suspended on the north pole as north pole=earth's magnetic south pole
What happens to the properties of a bar magnet if it were broken in thirds?
Nothing happens to properties because if it broken it still has north pole and south pole. Even if magnet broke into smallest piece it would still have same property.
What type of magnetism is present in a bar magnet?
The known magnetism in a bar magnet is electromagnetism.
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 to the bar magnet as it nears the U magnet the bar magnet will?
Move towards the U magnet so that the poles attach.
What does a electromagnet have that a bar magnet does not have?
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.
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 would be produced if you moved a bar magnet in and out of the wire coil?
An alternating current.
What happens to a bar magnet when it is cut in half?
The bar magnet becomes two smaller barn magnets.
How is earths magnetic field similar to that of a bar magnet?
electric current in a solenoid coil
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.
What can produced electricity?
Well, Many things can produce electricity. An easy way to produce electricity is to get a coil and pass a bar magnet through it.
How is an electromagnet differ from a regular bar or horseshoe magnet?
It requires a current through a coil of wires.
