What kind of magnetic field is produced by an infinitely long current carrying conductor?

What kind of magnetic field is produced by an infinitely long current carrying conductors.

Describe an experiment conducted by Oersted to demonstrate that magnetic field is produced by electric current.

A cylindrical region of magnetic field is produced by an electromagnet as shown in the figure. A wint carrying a current of 0.5 A is placed perpendicularly to the axis of the cylindrical region. If the magnetic field produced by the electromagnets is 2.0 T in strength and the radius of cylindrical region is 5 cm, find the magnetic force acting on the wire due to the magnetic field in the region.

Discuss Oersted's experiment to establish that magnetic field is produced due to current in a wire.
