What causes a magnetic field to be produced around a wire?
Current flows through a wire and produces a magnetic field.
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 magnetism be induced?
You can turn a magnetic field produced by a current on or off by simply turning the current on of off, You can change the direction of the magnetic field by reversing the direction of the current, You can also change the strength of a magnetic field produced by a current by looping the wire, by winding a wire with a current into many loops you strengthen the magnetic field in the center of the coil.
What statements describes the result of reversing the current in a current-carrying in a magnetic field?
When the current is reverted, the magnetic field will also be reverted.
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 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.
The direction of a magnetic field produced by an electric current depends on the direction of the what?
Flow of the current.
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.
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.?
No. More current will result in more magnetic field.
What shape is the magnetic field produced when current is passed through wire?
CIRCULAR
What causes a magnetic field to be produced around a wire?
Current flows through a wire and produces a magnetic field.
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.
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.'
