Does coil of wire carrying a current have a magnetic field?
yes
What is a coil of wire that when carrying a electric current produces a magnetic field?
No field
If a conductor carrying an alternating current is formed into a coil the magnetic field that is generated?
If the current is alternating, the magnetic field will also be alternating.
The magnetic field strength inside a current-carrying coil will be greater if the coil encloses a?
If the coil encloses an iron rod, then the magnetic field strength inside a current-carrying coil will be increased. This occurs because the air path in the coil is made shorter by putting in the rod. This in turn causes an increase in the field.
Why deflection of the magnetic needle placed in a coil carrying current increases as the number of turns in the coil increases?
Deflection of the magnetic needle placed in a coil carrying current increases as the number of turns in the coil increase because as the number of turns in the coil increases the strength of the magnetic field also increases.
If a conductor carrying an alternating current were formed into a coil the magnetic field that is generated?
Will cancel out and become zero
Does a coil carrying electric current create a magnetic field?
No, The magnet rotates/moves through the coil, inducing a current into the coil by disturbing the coils magnetic field. A transformer works the exact same way.
Name two devices which use current carrying conductor and magnetic field?
One device for increasing the magnetic field surrounding a current carrying wire, is to wrap the conductor into a set of co-axial coils. A second device is to include a ferromagnetic material in the core of such a coil.
How can you say that ac emf is induced in the coil?
When we place a current carrying conductor in a magnetic field emf is induced in a coil. we can knoe it by connecting voltmeter.
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
For a current carrying coil if the current is doubled then the field strength is?
doubled
Once a current flows through the coil does it become a magnet?
ANY flowing current is surrounded by a magnetic field. The coil simply makes the magnetic field stronger.
