What is the theoretical magnetic field around a current-carrying conductor which is an infinitely long cylinder?...
What is the theoretical magnetic field around a current-carrying conductor which is an infinitely long cylinder? What is the theoretical magnetic field around an infinitely long solenoid or planar sheet? (Use Ampere’s law to obtain these expressions). Note in particular the different dependence of the magnetic field on position for the two current geometries you have chosen.
please clear answer explaining the theory

An infinitely long conductor carrying current is bent at a right angle as shown in Figure 1. Point Pis located a distance b from the corner of the wire. Only one section of this current contributes to the magnetic field at pt. P. Why? The general formula (derived from the Biot-Savart Law) for the magnitude of the magnetic field a distance a away from a thin, straight conductor is: B = f (sin 8, - sin 02) For this problem,...
