What causes a magnetic field to be produced around a wire?
Current flows through a wire and produces a magnetic field.
Why is the magnetic field produced by a cylindrical solenoid is similar to a cylindrical permanent magnet?
Simple Answer:The shape of the magnetic field of a uniformly wound solenoid is very nearly identical to the field produced by a uniformly magnetized permanent magnet with the same physical shape as the solenoid.For the Experts:This is a consequence of the mathematical equivalence of the source of the magnetic field as created by a current and the source of a magnetic field as created by the curl of the magnetization density of permanent magnet.
How would you describe the magnetic field produced by a current in a straight wire?
Yes. It depends on its resistivity
How is mechanical force produced on a wire when it is passed through a wire in a magnetic field?
The movement through a magnetic field will induce a voltage; if there is a closed circuit, that will produce a current. The current, in turn, will have a magnetic field, which will interact with the external magnetic field. The direction of the interaction will be such that energy is conserved, i.e., it will tend to slow the wire down.
How can we increase the size of the magnetic field?
To increase the size of a magnetic field, you can enhance the current flowing through a conductor, as the magnetic field strength is directly proportional to the current. Additionally, using a core material with high magnetic permeability, such as iron, can concentrate and strengthen the magnetic field. Increasing the number of turns in a coil (solenoid) also amplifies the magnetic field produced. These methods can be combined for a more significant effect.
What are the three main characteristic of a magnetic field produced by current?
The three main characteristics of a magnetic field produced by current are: Direction: The field lines form closed loops and follow the right-hand rule. Strength: The strength of the field is directly proportional to the current flowing through the conductor. Distance: The magnetic field strength decreases as you move away from the current-carrying conductor.
What is produced around a wire that has a current?
Magnetic field.
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.
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 causes a magnetic field with no current?
A permanent magnet can create a magnetic field with no current. This is due to the alignment of the magnetic domains within the material, which results in a net magnetic field. The magnetic field produced can attract or repel other magnets or magnetic materials in its vicinity.
Current passing through a conductor is increased from 10 A to 15 A. This decreases the strength of the magnetic field produced by the conductor.?
Increasing the current passing through a conductor results in a stronger magnetic field, not a weaker one. Therefore, increasing the current from 10 A to 15 A should increase the strength of the magnetic field produced by the conductor.
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.
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.
