EXPERIMENT 12 Current Balance Introduction The current balance is used to measure the force of repulsion between identical, oppositely di-rected, currents in parallel conductors. In this experiment you will: 1) Determine how the magnetic force of one current-carrying conductor on a parallel current-

In this experiment you will use a current balance in which the upper conductor is free to pivot on knife edges. The upper conductor is balanced so that the wires are a small distance apart.
Experiment 18: The Current Balance. Advance Reading. Text: Magnetic force, magnetic field. Objective. The objective of this experiment is to measure the ef-fects of a magnetic field on a current carrying conduc-tor. Theory. A magnetic field exerts a force, FB, on a moving charge. The magnitude of FB is: FB = qvB sin θ (18.1)
The intertemporal approach views the current-account balance as the outcome of forward-lookingdynamic saving and investment decisions. This paper, a chapter in the forthcoming third volume of the Handbook of International Economics, surveys the theory and empirical work on the intertemporal approach as it has developed since the early 1980s.
He finds that the proposed government includes two kinds of checks and balances: vertical checks and balances wherein the state governments who are more numerous will act as a check on federal government power (discussed further in the next section), and horizontal checks and balances within the structure of the federal government itself.
In theory, the true exchange rate between two countries should reach a point of equilibrium that equal-ises the costs of goods in both countries, but other factors such as govern-ment intervention, transport costs, and so on mean that this theoretical equilibrium is never reached.
