Question 1 Given the proposed magnetic circuit below. We assume that the magnetic flux is linked by the coil and it is confined to the magnetic core. The magnetic circuit is characterized by the following: Hy = 103 N = 0.5 × 10³ turns i = 100 mA l = 100 mm N turns h = 10 cm 11 = 80 mm 12 = 0.09 m 1.1 Calculate the flux on the magnetic structure. 1.2 Calculate the flux density on the magnetic structure 1.3 Calculate the field intensity on the magnetic structure.
Ampere Circuital Law
Ampere's Law states that "for any closed loop path, the sum of the length elements times the magnetic field in the direction of the length element is equal to the permeability times the electric current enclosed in the loop.”
Current Density
To design the electrical and electronic system, the current density is an important factor. The designer current level is the factor on which the circuit performance depends and with the help of the dimensions of the conducting current the current density is then determined. For instance, despite the lower current demanded by smaller devices as integrated circuits are reduced in size, there is a type of trend in achieving the higher device number in even smaller chip areas. The current density is increased in this region at higher frequencies because the conducting region in a wire becomes confined and this is known as the skin effect. The consequences increase as the current densities become higher.
