PHY2061 R. D. Field Department of Physics chp33_5.doc University of Florida Ampere’s Law Examples Example ( Infinite Straight Wire with radius R ): An infinitely long straight wire has a circular cross section of radius R and carries a uniform current density J along the wire. The total current carried by the wire is I . What is the magnitude of the magnetic field inside and outside the wire? Answer: Br kI r krI R out in () = = 2 2 2 . Example ( Infinite Solenoid ): An infinitely long thin straight wire carrying current I is tightly wound into helical coil of wire ( solenoid ) of radius R and infinite length and with
