in a similar way and always come in pairs: every north pole is yoked to a south pole. 3. An electric current in a wire creates a circular magnetic field around the wire‚ its direction depending on that of the current. 4. A current is induced in a loop of wire when it is moved towards or away from a magnetic field‚ or a magnet is moved towards or away from it‚ the direction of current depending on that of the movement.

magnetization. Direct magnetization occurs when the electric current is passed through the test object and a magnetic field is formed in the material. Indirect magnetization occurs when no electric current is passed through the test object‚ but a magnetic field is applied from an outside source. The magnetic lines of force are perpendicular to the direction of the electric current which may be either alternating current (AC) or some form of direct current (DC) (rectified AC).

borders included within the balance of payment? Are they current or financial account components? Remittances represent an inflow for developing countries‚ sometimes greater than financial aids. Developed countries such as US‚ from which remittances are sent‚ classify migrant remittances as current transfers in the current account. International transfers of money by private individuals‚ such as workers’ remittances‚ appear in the current account of the balance of payments as unilateral transfers

All batteries have a "+" and "-" terminal. Electric current is a flow of atomic particles called electrons. Certain materials ‚ called conductors‚ allow electrons to flow through them. Most metals (copper‚ iron) are good conductors of electricity. Electrons will flow from the "-" electrode of a battery

CHAPTER 1 : INTRODUCTION 1.1 Introduction Recently‚ we often hear cases of theft manhole made of steel. These thefts often occur because the steel is very valuable when sold. One of my neighbors asked if there are tools that can prevent theft drains. From there I got the idea to create an alarm that can prevent theft from stealing the drain cover becoming increasingly. We begin by examining the case drain theft either inside or outside the country. Too many cases that have occurred that resulted

FACTS (Flexible AC Transmission System) and HVDC (High Voltage Direct Current) are controllable devices whose functions are to enhance the security‚ capacity and flexibility of power transmission systems. Application of these components in power systems implies an improvement of transient and voltage stability‚ power oscillation
