âA higher salary or wage that is a higher price in the labor market leads to a decrease in the quantity of labor demanded by employers. A lower salary or wage leads to an increase in the quantity of labor demanded. A higher price for labor leads to a higher quantity of labor supplied.
Electric Current. If the two requirements of an electric circuit are met, then charge will flow through the external circuit. It is said that there is a current-a flow of charge. Using the word current in this context is to simply use it to say that something is happening in the wires-charge is moving.
Can some one please explain to me why electricity flowing though a copper coil generates a magnetic field or where I could possibly find that information? An electric current (a flow of electric charge) has an associated magnetic field regardless of the material (or space) the flow occurs in. This is a fundamental part of electromagnetism, rooted in observation, and quantified in Ampere's Law.
