Lecture notes by Prof. A. K. JAIN‚ IIT ROORKEE CHAPTER 13: The Deuteron (Lecture time: 2 Hours) Deuteron is the simplest nuclear system where nuclear forces come into play. It is the “Hydrogen Atom” of nuclear physics. It may also be viewed as the simplest odd-odd nucleus‚ having one proton and one neutron. It exhibits features which require the use of a number of new concepts such as exchange force‚ tensor force etc. Of three possible states of two nucleon system‚ di-neutron‚ di-proton‚ and deuteron

method for collection of data | | Total | | Aim: To study the effect of spacing of the coils on the strength of an electromagnet Apparatus Required: * An iron nail (around 8 cm) * A copper wire (15 cm) * Vernier Logger Pro * Magnetic Field sensor * Battery * Switch * Sand Paper Background Theory: Some metals such as nickel and iron can be magnetised using an electromagnet. The strength of the electromagnet depends on various factors which include the current‚

converter has inherent advantages such as zero voltage switching (ZVS) or zero-current switching (ZCS) of the switches‚ high-voltage gain‚ minimum circulating current and high efficiency. Keywords: Artificial heart—Transcutaneous energy transmission—Magnetic field immunity of the system. Introduction: With the rapid development of life science and bio-engineering‚ the research of implanted medical device‚ especially the totally artificial heart (TAH)‚ has made great progress

(CETS)‚ by which electrical energy may be transmitted‚ without electrical connection or physical contact‚ through nonmagnetic media of low conductivity. The CETS‚ which has been used to transfer up to 5 kW across a 10-mm gap‚ employs high-frequency magnetic coupling and enables plug-in power connections to be made in wet or hazardous environmental conditions without the risk of electric shock‚ short circuiting‚ or sparking. Energy may be transmitted without the necessity for accurately manufactured

Kevin Williams Project 1 The use of electricity and magnetism in transportation When Benjamin Franklin discovered electricity‚ it was probably one of the biggest discoveries known to mankind. Even though our dependence of electricity is a lot‚ however at the same time it’s easy to forget how dependent we actually are on it. Electricity always has and always will play a huge part in our everyday life. It’s hard to imagine humanity without it. When it comes to transportation‚ it is going to rewrite
