What is produced around a wire that has a current?
Magnetic field.
Moving a wire through a magnetic field does not create a current flow in a wire?
Not true - Moving a wire through a magnetic field doescreate a current flow in a wire.false
When does an electromagnet produce a magnetic field?
A magnetic field is generated whenever a current is passing through a 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.
What is produced when a magnetic field moves relative to a closed wire loop?
Faraday says you will induce a current in 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 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 causes a magnetic field to be produced around a wire?
Current flows through a wire and produces a magnetic field.
What is magnetic field produced by a current flowing through a wire?
A current flowing through a wire produces a magnetic field around the wire. The direction of the magnetic field is determined by the right-hand rule, where if you point your thumb in the direction of the current, your fingers will curl in the direction of the magnetic field lines. The strength of the magnetic field is directly proportional to the current flowing through the wire.
What shape is the magnetic field produced when current is passed through wire?
CIRCULAR
What is produced around a wire that has a current?
Magnetic field.
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 a magnet field be produced around a wire?
By passing a current threw it.
Why does an iron core increase the magnetic field of a coil of wire?
An iron core increases the magnetic field of a coil of wire because iron is a ferromagnetic material that easily magnetizes in the presence of a magnetic field. This enhances the magnetic field produced by the current flowing through the wire, resulting in a stronger overall magnetic field.
Which type of current is produced by a wire breaking magnetic field lines and changing the polarity?
An alternating current (AC) is produced when a wire cuts through magnetic field lines and experiences a change in polarity. This phenomenon is known as electromagnetic induction, where the changing magnetic field induces a current in 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.
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.
