Which happens to the magnetic field of a wire when you change the direction of the current in the wire?
The polarity of the magnetic field of a wire reverses when you change the direction of the current in the wire.
The direction of a magnetic field produced by an electric current depends on the direction of the what?
Flow of the current.
In an electromagnet as the electric current changes what happens to the magnetic field?
the magnetic field would constantly change, that's why the AC current is converted to DC current
What flows through a circuit and causes a magnetic field?
An electric current flowing through a circuit causes a magnetic field. This is due to the movement of electric charges, usually electrons, in the circuit. The magnetic field produced is perpendicular to the direction of the current flow.
How is the magnetic field of an eletromagnet controlled?
The intensity of the magnetic field (measured in Teslas) produced by an electromagnet is directly proportional to the current (measured in Amperes) passing through it's coil windings. Therefore, as long as other variables remain constant, one can vary the intensity of the magnetic field by varying the current. Specifically, the intensity of the magnetic field will vary by the same factor as the current, so if the current is halved, the intensity of the magnetic field will also be halved; and if the current is tripled, the intensity of the magnetic field will also be tripled.
What is produced around a wire that has a current?
Magnetic field.
What is lenz law of electromagnetic induction?
Lenz's law states that 'for a current induced in a conductor by a changing magnetic field, the current is in such a direction that its own magnetic field opposes the change that produced it.'
What are the three characteristics of magnetic field produced by a current?
.
What is the purpose of a magnetic field produced by charges in a current?
Depends whether Direct Current or Alternating Current. Only Alternating Current produces magnetic field.
What is electricomagnet?
An electromagnet is a type of magnet in which the magnetic field is produced by the flow of electric current. The magnetic field disappears when the current ceases.-wikipedia
How can you reverse the direction of the magnetic field in a wire produced by an electric current?
You can reverse the direction of the magnetic field by reversing the direction of the electrical current.
What is magnetoresistence?
The change in electrical resistance produced in a current carrying conductor or semiconductor on application of magnetic field H.
How does an electric coil works?
when u give supply to a coil then a current will be passed through it .naturally a magnetic field is produced around the c.c.c(current carrying conductor). when u make more turns in the same direction the whole magnetic field will be stronger than that of a wire has. andby lenz's law there will be an opposition to the changing current in a coil due to the change in magnetic field produced
Which happens to the magnetic field of a wire when you change the direction of the current in the wire?
The polarity of the magnetic field of a wire reverses when you change the direction of the current in the wire.
The direction of a magnetic field produced by an electric current depends on the direction of the what?
Flow of the current.
What is needed for electromagnetic induction?
An electric current is produced by the change in Magnetic flux over timeRead more: How_do_electromagnets_work
Will magnetic field is produced when current is passed through a thick conducting sheet?
Yes,,,a current carrying conductor wil produce magnetic field around it.
