A magnetic field is a change in energy within a volume of space. A magnetograph can be created by placing a piece of paper over a magnet and sprinkling the paper with iron filings. The particles align themselves with the lines of magnetic force produced by the magnet. The magnetic lines of force show where the magnetic field exits the material at one pole and reenters the material at another pole along the length of the magnet. It should be noted that the magnetic lines of force exist in three dimensions but are only seen in two dimensions in the image.
The current must be changing. Say thank you to Faraday.
Current flows through a wire and produces a 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.
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.
Yes. It depends on its resistivity

Magnetic field.
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.
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.
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 current flow. The magnetic field will form circular loops around the current-carrying wire, following the right-hand rule.
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
You can reverse the direction of the magnetic field by reversing the direction of the electrical 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.
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.
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.
Yes,,,a current carrying conductor wil produce magnetic field around it.
