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

An historical account of the development of the use of magnetic media in radio‚ television and film applications accompanies practical insights in to the conservation requirements of the medium. There are two recording systems that are widely used such as analogue recording and digital recording. A discussion

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‚

Place the compass on the left side of the coil so that the compass center lies along the axis of the coil. (The y-component of the magnetic field is zero along the axis of the coil.) 12. Move the compass along a semicircular path above the coil until you’ve put it on the opposite side of the coil. Describe what happens to the compass needle. 13. Move the compass along a semicircular

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

-Faraday- his major contributions were in the fields of electromagnetism and electrochemistry. He explained the basis of magnetic field through his studies on the effects of magnetic field around a conductor which carried Direct Current (DC). In 1831‚ Faraday made one of his most renowned discoveries‚ the principle of electromagnetic induction by using the "induction ring". The electricity was generated by means of electromagnetic effect. This was the first version of an electric transformer. He

The race for a practical generator begins. • Faraday’s disk 1832-1860 Various generator schemes are tried‚ mostly employing permanent magnets to create the necessary magnetic field. Ampère and Pixii make the first hand-cranked version (1832); C.G. Page proposed a reciprocating analogue of the steam engine (1850); and H. Wilde made the commercially successful Alliance generator (1866) for powering arc lamps in lighthouses

A.C current meters Introduction An ammeter is a measuring instrument used to measure the electric current in a circuit. Electric currents are measured in amperes (A)‚ hence the name. Neither type of basic dc PMMC meter movement will correctly indicate an alternating current. There are‚ however‚ four basic types of meter movement that will indicate ac values:- Thermocouple Hot wire Electrodynamometer Iron-vane Electrodynamic ammeters An electrodynamic meter uses an electromagnet instead
