• We know that an electric current produces a magnetic field. Ampere, after carrying out a series of experiment. generalized his results into a law known as Ampere circuital law by which the magnetic flux density B at any point due to a current carrying conductor can be easily computed as explained below:

• Consider a closed path in the form a arete of radius r enclosing the current carrying wire. This closed path is referred as Amperean path. Divide this path into small elements of length like AL. Let B be the value of flux density at the site of AL. Determine the value of B.AL. If 0 is the angle between B and AL. then  B..\L = BAL cos0

• Cathode ray oscilloscope (CRO) is a very versatile electronic instrument which is. in fact, a high speed graph plotting device. It works by deflecting beam of electrons as they pass through uniform electric field between the two sets of parallel plates. The deflected beam then falls on a fluorescent screen where it makes a visible spot.
