Introductory Physics II Electricity, Magnetism and Optics by Robert G. Brown Duke University Physics Department Durham, NC 27708-0305 rgb@phy.duke.edu Magnetic poles refer to the ends of a magnet where the power of attraction or repulsion is greatest. They are closer together where the field is stronger.

The diagram below the magnetic field patterns between two magnets P and Q. This is called the directional property of a magnet. Thevenin theorem, Norton theorem, Superposition theorem, Reciprocity Theorem, Maximum Power Transfer theorem. In this method a magnetic material bar is repeatedly stroked using one end of a strong magnet. The stroking is repeated several times while keeping the inclination of the magnet the same. The soft iron rods and rings are used in magnetic shielding where some electrical measuring instruments and watches are shielded and protected from stray magnetic fields. Physics Notes for Class 12 Chapter 5 Magnetrism And Matter The property of any object by virtue of which it can attract a piece of iron or steel is called magnetism. Current Loop as a Magnetic Dipole and its Dipole Moment (Analogy with Electric Dipole).Ampere’s Circuital Law and its application to (1) Solenoid and (2) Toroid. • Any magnetic/magnetized object has a North and South pole. Capacitor (parallel plate, spherical, cylindrical) filled with dielectric. Leave a Comment / IIT JEE, Entrance Exam, PHYSICS / By Abhishek. Magnetisation of a single crystal costs a large amount of energy of magnetisation = Balanced by anisotropy energy - spins only like to align along particular crystal directions - energy cost is K per electron spin ∫B0.dM Domains in real crystals Single ‘whisker’ of iron Larger crystal of Nickel Domains can be ‘pinned’by the pre N/B This disadvantage can be avoided by use of double stroke method. These are the Magnetism and Matter class 12 Notes prepared by team of expert teachers. Or else you can take the printout of the PDF for your future reference. It is freely available in its entirety in a downloadable PDF form or to be read online at: ... A lecture note style textbook intended to support the second semester (primarily the dynamical portion, little statics covered) of a two semester course of graduate Classical Electrodynamics. Here are some important questions and study notes related to Magnetism. Lecture Notes: PDF Supplementary Slides: PDF Lecture 2(1/20/2011) "Electric Charge and Force" Lecture Notes: PDF Supplementary Slides: PDF Lecture 3 (1/25/2011) This is because repulsion can only occur between like poles of magnets. Energy stored in a Magnetic Field. • Any magnetic/magnetized object has a North and South pole. Assignment. The property of any object by virtue of which it can attract a piece of iron or steel is called magnetism. Consider two bar magnets with opposite poles adjacent. Methods of magnetisation. MIT OpenCourseWare is a free & open publication of material from thousands of MIT courses, covering the entire MIT curriculum.. No enrollment or registration. Name:_ Regents Physics Chapter 11- Magnetism Magnetism A magnet is a material in which the spinning electrons of its atoms are Answers of assignment are given at the end of each assignment with complete solutions. The magnets magnetize soft iron keepers through induction.The aligned dipoles form a closed loop or chain round the magnets and the keepers, with no free poles. The magnetic dipole moment of a magnetic dipole is given by M = m × 2I where, m is pole strength and 2I is dipole length directed from S to N. The SI unit of magnetic dipole moment is A-m 2 or J/T. Find materials for this course in the pages linked along the left. 1. State one application of magnetic shielding.

Lect 01: Biot Savart Law. Each topic is explained in very easy language with colored diagrams. Series LCR Circuit: (1) Resonance, (2) Power Dissipation, and (3) Quality Factor, and (4) Band Width. If a magnet is suspended by a thread and is free to rotate it rotates and finally rests in the in the North south direction. Lenz’s Law. It is a vector quantity and its direction is from South pole to North pole. So, go ahead and check the Important Notes for Class 12 Physics Magnetism. In Cambridge, these courses are called Part IB Electromagnetism and Part II Electro-dynamics. Magnetic field lines get concentrated along the soft iron. Class 12 Physics Revision Notes for Chapter 4 - Moving Charges and Magnetism - Free PDF Download Magnetism and moving charges, i.e., electricity is being studied for more than a century now. With the help of Notes, candidates can plan their Strategy for particular weaker section of the subject and study hard. The graphs below are for two magnetic materials. Electrostatic energy of a charged sphere. The field is stronger near the poles of the magnet and is weaker farther away from the poles. Magnetic tapes used in audio and video recorders. Click here.
