to 15. The steps I would use would be to: 1. Using some magnetic manipulatives I would start with a group of 10 magnets in one group on a white board and 5 others in a different group on the board. I am using the magnets because they are easy to move around and the white board allows me to write and erase the name of the number down below the magnet. There is no pattern to the magnet placement in the large or small group. They are randomly placed inside the group. 2. I would start by

ANSWERS TO GUIDE QUESTIONS 1. What happens to the distribution of magnetic flux lines when the iron ring was placed in between the U-magnets? Magnetic Flux‚ by definition‚ is the measure of the quantity or the strength of the magnetic force in a given area‚ whether a closed or an open area. When the iron ring is placed in between the U-magnets‚ there has been a region by which has been enclosed‚ following the area of the iron ring. And according to Gauss’s Law for magnetism‚ the total magnetic

What is Magnetism? Properties of Magnets: Magnet: any material that attracts iron and materials that contain iron Magnets attract iron and materials that contain iron. magnets attract or repel other magnets. In addition‚ one part of a magnet will always point north when allowed to swing freely. Magnetic Poles: Magnetic Pole: any magnet with 2 ends‚ each is called a magnetic pole. Magnetic poles that are unlike attract each other and magnetic poles that are alike repel each other. Magnetic

field :- The region around a magnet where the force of attraction or repulsion can be detected is called magnetic field. Magnetic field around a magnet can be detected by using a magnetic compass. b) Magnetic field lines:- Magnetic field lines are the paths around a magnet along which the north pole of a magnetic compass needle tends to move. The magnetic field lines around a magnet can be observed by sprinkling iron filings around a magnet. It can also be observed by moving

Experiment 4 Measurement of e by Thomson’s bar magnet method. m Apparatus: Cathode ray tube (CRT) with power supply unit‚ one pair of bar magnets‚ high resistance voltmeter‚ magnetometer‚ stopwatch. Purpose of experiment: e To measure the specific charge‚ i.e. charge to mass ratio ‚ of an electron using m Thomson’s bar magnet method. Basic methodology: Electrons in a CRT are deflected in the vertical direction by applying a potential between the vertical deflection plates of the CRT.

TERM PAPER ON SUPERCONDUCTIVITY BY: VISHAL K YADAV (B.TECH 1ST yr) Superconductivity "The discovery of superconductors" The phenomenon of superconductivity‚ in which the electrical resistance of certain materials completely vanishes at low temperatures‚ is one of the most interesting and sophisticated in condensed matter physics. It was first discovered by the Dutch physicist Heike Kamerlingh Onnes‚ who was the first to liquefy helium (which boils at 4.2 Kelvin at standard pressure)

connected and disconnected.[1] Within two months‚ Faraday found several other manifestations of electromagnetic induction. For example‚ he saw transient currents when he quickly slid a bar magnet in and out of a coil of wires‚ and he generated a steady (DC) current by rotating a copper disk near the bar magnet with a sliding electrical lead ("Faraday’s disk").[8] Faraday explained electromagnetic induction using a concept he called lines of force. However‚ scientists at the time widely rejected his
