The measurement of the distribution of induced currents using an induction sensor located and moved along the radius of the conductor surface and the direct measurement of the induced current density by the voltage drop at a given gap in the conductor.
In this design, base current makes stator field flux, harmonic current makes induced current in rotor winding, this rotor current is rectified by diode and makes rotor field flux, and then it produces torque by stator field flux and rotor field flux.
Induced currents in embryo under 220 kV transmission line when mothers' hands angle with respect to her body is degree for (x, y, z) = (0,0,8), (0,10,8), (0,20,8), (0,30,8), (0, 40, 8) are shown in figure 3.
According to Lenz's Law, which describes the direction of induced currents in the presence of varying fields, the induced currents oppose the change in applied magnetic field and possess a unique field of its own.
The comply with the limits set by the directive, lighting equipment manufacturers have to ensure their products pass EMC standards for emissions and also do not produce electromagnetic fields above limits for induced current density over the frequency range 20kHz to 10MHz.
Therefore, the induced current source amplitude is given by
In this composite model due to the incident tapered electric field and the coupling scattering between the target and the rough surface, the induced current [J.
With the help of the magnetic fields, the induced current density can be calculated by Eq.
3), induced current will circulate in the tube whose magnetic field opposes motion of the magnet by Lenz's law.
If the nearby conductor is carrying its own current, then the induced current can alter the current distribution over the cross-section.
Antennas located near ground will experience signal attenuation for two main reasons: induced current in the antenna from nearby reflections and signal interference from reflected waves.
