Opportunity cost The true cost of something is what you give up to get it.(This includes not only the money spent in buying (or doing) the something‚ but also the economic benefits (UTILITY) that you did without because you bought (or did) that particular something and thus can no longer buy (or do) something else.) Factors of production The ingredients of economic activity: land‚ labor‚ capital and enterprise. Economic Development The scope of economic development includes the process and

Advantages 8 References 9 Magnetic Abrasive Finishing (MAF) Process Harry P. Coats first patented MAF in 1938. Although US originate this idea‚ most of later period development is done by USSR + Bulgaria. Japanese explore the technology for polishing purpose. Other countries in this field are: India‚ CIS‚ England‚ France‚ and Germany etc. Process details: • In MAP‚ w/p is kept between the two magnets & the air gap in-between the w/p & the magnet is filled with Magnetic Abrasive Particles (MAPs)

PHYSICS FOR SCIENTIST AND ENGINEERS LABORATORY EXPERIMENTS EXPERIMENT 5 (Assignment) EXPERIMENT 5 – MAGNETIC FIELDS OBJECTIVES 1. To study the workings of magnetic fields. 2. To determine the North and South poles of magnets and magnetic field lines. 3. To understand the attractive and repulsive forces acting on it. INTRODUCTION Electric current is defined as the rate at which charge flows through a surface. As with all quantities defined as a rate‚ there

according to the magnetic source‚ the magnetic separator can be divided to permanent magnetic separator and electromagnetic separator. 2‚ according to the strength of magnetic field‚ it can be divided into: (1) Weak magnetic separator‚ the surface magnetic strength HO=72-136 KA/m‚ magnetic force HgradH= (2.5-5.0) 1011 A/m. (2) Middle magnetic separator‚ the surface magnetic strength HO=160-480 KA/m; (3) Strong magnetic separator‚ the surface magnetic strength HO=480-1600 KA/m‚ magnetic force HgradH=

Explain what it means when we say a substance is magnetic. A substance can be picked up by a magnet. Discuss the relationship between electric and magnetic fields. The magnetic field will be perpendicular to the electric field and vice versa Before you begin your lab‚ you need to form a hypothesis that reflects which material‚ voltage‚ and number of winds you think will produce the strongest electromagnet. Record your hypothesis as an if then statement. If I use copper‚ 100 volts‚ large thickness
