Based on the right-hand grasp rule for a coil of wire, shown in the diagram on the below, is the magnetic field from the sim the same direction as the direction of the field from your right hand [thumb]? Should it be the same or opposite? Please explain your answer. Hint: Lenz's law B The right-hand rule for the magnetic field produced by a current in a loop: [Insert answer here]
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.
