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.
As discussed previously, a magnetic field is a change in energy within a volume of space. The magnetic field surrounding a bar magnet can be seen in the magnetograph below.

What the characteristics of the magnetic field produce by flowing current?
1)they start from north pole and end's in south pole.
2)they never intersect or cross each other.
3)
The magnetic field produced by a current has three distinct characteristics. The field can be turned on or off, have its direction reversed, or have its strength changed.
The current must be changing. Say thank you to Faraday.
Current flows through a wire and produces a magnetic field.
Yes. It depends on its resistivity
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.
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.

Magnetic field.
Depends whether Direct Current or Alternating Current. Only Alternating Current produces magnetic field.
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.
Flow of the current.
Yes,,,a current carrying conductor wil produce magnetic field around it.
The current must be changing. Say thank you to Faraday.
No. More current will result in more magnetic field.
CIRCULAR
Current flows through a wire and produces 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.
