What else can I help you with?
A magnetic field produced by a current has the characteristic?
The current must be changing. Say thank you to Faraday.
What is the shape of magnetic lines force in case of a straight current carrying conductor?
The shape of the magnetic field lines around a straight current-carrying conductor is circular, with the conductor at the center of each circular loop. These magnetic field lines form concentric circles around the conductor, perpendicular to the direction of the current flow.
How could straight copper wire produce magnetic field lines?
The copper by itself will do nothing of the sort. It will be surrounded by magnetic field lines if a current flows through it. It is the current that produces the magnetic field lines.
Why will an electric current not be produced in a wire that is exposed to a stationary magnetic field?
An electric current will not be produced in a wire exposed to a stationary magnetic field because current generation relies on a change in magnetic flux through the wire, as described by Faraday's law of electromagnetic induction. When the magnetic field is stationary, there is no variation in magnetic flux, and thus no electromotive force (EMF) is induced in the wire. Therefore, without the movement or change in the magnetic field, electrons in the wire do not experience a net force to create a current.
What type of current does a straight current carrying wire produce?
A straight current-carrying wire produces a magnetic field around it, which can be described as a circular magnetic field perpendicular to the direction of current flow. This magnetic field is responsible for creating a force on any nearby moving charges.
How will you describe the magnetic field around a straight current-carrying wire?
the magnetic field gets stronger with increasing distance from the wire
What is produced around a wire that has a current?
Magnetic field.
Why is the magnetic field strength greater inside a current carrying wire than about a straight section of wire?
The magnetic field strength is greater inside a current-carrying wire because the magnetic field lines produced by the current are concentrated within the wire due to the close proximity of the electric charges moving through it. In contrast, around a straight section of wire, the magnetic field lines spread out into the surrounding space, resulting in a weaker magnetic field intensity.
What are the three characteristics of magnetic field produced by a current?
.
What are three ways you can change the magnetic field produced by a current?
You can change the magnetic field produced by a current by altering the strength of the current flowing through the conductor, changing the direction of the current flow, or varying the distance between the conductor and the point where you are measuring the magnetic field.
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.
The direction of a magnetic field produced by an electric current depends on the direction of the what?
The direction of a magnetic field produced by an electric current depends on the direction of the current flow. The magnetic field will form circular loops around the current-carrying wire, following the right-hand rule.
Describe what happens when you hold a compass close to a wire carrying a current?
When a compass is held close to a wire carrying a current, the magnetic field produced by the current will deflect the compass needle. This happens because a magnetic field is generated around the wire due to the flow of current, and the compass needle aligns itself with this magnetic field. The deflection of the compass needle can be used to determine the direction of the current in the wire.
What type of magnet is produced by an electric current?
An electromagnet is produced by an electric current. When an electric current flows through a coil of wire, it generates a magnetic field. The strength of the magnetic field can be controlled by adjusting the amount of current flowing through the coil.
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 happens in earth interior to produce earths magnetic field describe the layer where the magnetic field is produced?
What escapes the crust is what we observe as the earths magnetic field. The outer core is a rotating mass of fluid metal that induces an electrical current which in turn generates the magnetosphere.
