This Freshman Advising Seminar surveys the many applications of magnets and magnetism. To the Chinese and Greeks of ancient times, the attractive and repulsive forces between magnets must have seemed magical indeed. Through the ages, miraculous curative powers have been attributed to magnets, and magnets have been used by illusionists to produce "magical" effects. Magnets guided ships in the Age of Exploration and generated the electrical industry in the 19th century. Today they store information and entertainment on disks and tapes, and produce sound in speakers, images on TV screens, rotation in motors, and levitation in high-speed trains. Students visit various MIT projects related to magnets (including superconducting electromagnets) and read about and discuss the history, legends, pseudoscience, science, and technology of types of magnets, including applications in medicine. Several short written reports and at least one oral presentation will be required of each participant.

Look inside a resistor to see how it works. Increase the battery voltage to make more electrons flow though the resistor. Increase the resistance to block the flow of electrons. Watch the current and resistor temperature change.

Look inside a battery to see how it works. Select the battery voltage and little stick figures move charges from one end of the battery to the other. A voltmeter tells you the resulting battery voltage.

This new version of the CCK adds capacitors, inductors and AC voltage sources to your toolbox! Now you can graph the current and voltage as a function of time.

This introductory, algebra-based, two-semester college physics book is grounded with real-world examples, illustrations, and explanations to help students grasp key, fundamental physics concepts. This online, fully editable and customizable title includes learning objectives, concept questions, links to labs and simulations, and ample practice opportunities to solve traditional physics application problems.

Experiment with conductivity in metals, plastics and photoconductors. See why metals conduct and plastics don't, and why some materials conduct only when you shine a flashlight on them.

It this exercise the students will discover that pure water does not conduct electricity and that dissolving different substances in water may or may not cause it to conduct electricity.

This three credit course offeredat Macomb Community Collegeprovides an introduction toalternating current (AC)motors, AC motor controls, and AC motor applications tobattery electric and hybrid electric vehicles (BEVs and HEVs). Course topics include fundamental concepts of electricity and magnetism, AC motors, traction motors, AC synchronous permanent magnet motors, HEV/BEV energy storage and control systems, adjustable frequency drives, and modeling of various components associated with electric drivevehicles in MatLab and Simulink software. Included educational materials for this course are a syllabus and PowerPoint presentations. Homework assignments and exams are not included. This course is required as a part of MCC's Electric VehicleDevelopmentTechnology Certificate and the course outline is as follows: introduction to single-phase motors, motor operation theory, basic motor controls, introduction to three phase motors, three-phase motor controls, theory of operation for adjustable frequency drives, configuring drive parameters, simulation of parameters using MatLab software, and simulation of electric vehicle parameters using Simulink software.

Play hockey with electric charges. Place charges on the ice, then hit start to try to get the puck in the goal. View the electric field. Trace the puck's motion. Make the game harder by placing walls in front of the goal. This is a clone of the popular simulation of the same name marketed by Physics Academic Software and written by Prof. Ruth Chabay of the Dept of Physics at North Carolina State University.

Play ball! Add charges to the Field of Dreams and see how they react to the electric field. Turn on a background electric field and adjust the direction and magnitude. (Kevin Costner not included).

This is an algebra-based introductory course for electricity physics. It is intended to be a comprehensive introductory course in all electricity aspects.

Electrical, optical, magnetic, and mechanical properties of metals, semiconductors, ceramics and polymers. Discussion of roles of bonding, structure (crystalline, defect, energy band and microstructure) and composition in influencing and controlling physical properties. Case studies drawn from a variety of applications including semiconductor diodes, optical detectors, sensors, thin films, biomaterials, composites, and cellular materials.

In this introduction to light energy, students learn about reflection and refraction as they learn that light travels in wave form. Through hands-on activities, they see how prisms, magnifying glasses and polarized lenses work. They also gain an understanding of the colors of the rainbow as the visible spectrum, each color corresponding to a different wavelength.

This is a comprehensive science textbook for Grade 10. You can download or read it on-line on your mobile phone, computer or iPad. Every chapter comes with video lessons and explanations which help bring the ideas and concepts to life. Summary presentations at the end of every chapter offer an overview of the content covered, with key points highlighted for easy revision. Topics covered are: skills for science, classification of matter, states of matter, kinetic molecular theory, the atom, the periodic table, chemical bonding, transverse pulses, transverse waves, longitudinal waves, sound, electromagnetic radiation, particles, compounds, physical and chemical change, representing chemical change, magnetism, electrostatics, electric circuits, reactions in aqueous solution, quantitive aspects of chemical change, vectors and scalars, motion in one direction, mechanical energy, the hydrosphere. This book is based upon the original Free High School Science Text series.

Play with a bar magnet and coils to learn about Faraday's law. Move a bar magnet near one or two coils to make a light bulb glow. View the magnetic field lines. A meter shows the direction and magnitude of the current. View the magnetic field lines or use a meter to show the direction and magnitude of the current. You can also play with electromagnets, generators and transformers!

Light a light bulb by waving a magnet. This demonstration of Faraday's Law shows you how to reduce your power bill at the expense of your grocery bill.
