What else can I help you with?
What is produced when a magnetic field moves relative to a closed wire loop?
Faraday says you will induce a current in the wire.
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.
Do field lines around a current wire look different from those around a bar magnet?
Yes. The field lines of a bar magnet emerge from one end, curve around, and stop at the other end. The field lines around a current-carrying wire are circles, with the wire passing through their centers.
What will happens to current when cable length increases?
With a constant voltage and increase in wire length will increase the end to end resistance and therefore the current will decrease.
What is a current-carrying wire?
A wire with some resistance and a voltage applied to it The amount of current I passing this wire is V/R
What is produced around a wire that has a currrent?
When a current flows through a wire, a magnetic field is produced around the wire. This magnetic field is perpendicular to the direction of the current flow and its strength is proportional to the amount of current flowing through the wire.
What is produced around a wire when an electric current flows through a wire?
A magnetic field is produced around a wire when an electric current flows through it. This magnetic field is directed along circular lines around the wire.
What is the magnetic field that is produced around a wire when an electrical current flows through it?
When an electrical current flows through a wire, it creates a magnetic field around the wire.
How can a magnet field be produced around a wire?
By passing a current threw it.
If the current in a wire is directed upward what is the direction of the magnetic field produced by the current?
The magnetic field produced by a current-carrying wire points in a circular direction around the wire, following the right-hand rule. In this case, with the current directed upward, the magnetic field would circle around the wire in a clockwise direction when viewed from above.
What causes a magnetic field to be produced around a wire?
Current flows through a wire and produces a magnetic field.
What is the right hand rule for current in a wire and how is it applied to determine the direction of the magnetic field produced by the current flow?
The right-hand rule for current in a wire states that if you point your right thumb in the direction of the current flow, then the direction your fingers curl around the wire represents the direction of the magnetic field produced by the current. This rule helps determine the relationship between the direction of current flow and the resulting magnetic field around the wire.
What does a wire with current going through it produced around it?
A wire with current flowing through it produces a magnetic field around it according to Ampere's law. The direction of this magnetic field is determined by the right-hand rule. The strength of the magnetic field is directly proportional to the current in the wire and inversely proportional to the distance from the wire.
What is the difference in the direction of the magnetic field produced around conductor by dc flow and ac flow?
The direction and amplitude of the magnetic field around a wire depend on the direction and amplitude of the current through the wire. When the wire carries DC, the direction and amplitude of the current in the wire are constant, so the direction and amplitude of the magnetic field around the wire are constant. When the wire carries AC, the direction of the current in the wire is periodically reversing and its amplitude typically changes, so the direction of the magnetic field around the wire is periodically reversing and its amplitude is typically changing.
Why does a current carrying wire produce no magnetic field?
A current-carrying wire does produce a magnetic field around it according to Ampere's law, which states that a current generates a magnetic field. This phenomenon is the basis for the operation of electromagnets and the magnetic field produced is directly proportional the current flowing through the wire.
How are electromagnectic waves made?
it is produced by the aid of the: an electromagnetic wave is produced when for example when a wire is connect to a current the wire will be changing gradually as is changing
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.
