PHYS 102x serves as an introduction to electromagnetism, including charge, electric and magnetic forces, induction, current, and resistance.
PHYS102x serves as an introduction to electricity and magnetism, following the standard second semester college physics sequence.
Before your course starts, try the new edX Demo where you can explore the fun, interactive learning environment and virtual labs. Katherine Van Leeuwen Katherine Van Leeuwen is an undergraduate physics major at Rice University with strong interest in education. Magnetic fields can be created either by placing, a permanent magnet or by supplying current through a solenoid. The lines of force of magnetic field are radiated from the north (N) pole to the south (S) pole. Since the flux lines are something like elastic bands, the lines linking two unlike magnetic poles always try to shorten themselves. In addition to the heating effect of electric current, it also produces a magnetic field surrounding the conductor carrying the current .
The amount of flux crosses a unit area perpendicularly, in a magnetic field is known as magnetic flux density. In 3.15x we will explore the electrical, optical, and magnetic properties of materials and learn how electronic devices are designed to exploit these properties. Coils, Solenoids, and Electromagnets, the function is convert Electricity into magnetism and finaly to mechanical force.
Their functions are: Linear Pull Push, Self Latching, Keeping, Holding, dual latching, bi-stable.
Their structures are: Open Frame (C frame, D frame, U frame, Box frame) Solenoids, Tube, Tubular, cylinder, cylindrical shape. They are widely used in industry automation, social automation, office an home life automation.

It begins with electric charge in matter, the forces between charges, the electric field, Gauss's Law, and the electric potential. She has developed physics curricula with Breakthrough Austin and with StemScopes, and taken courses on the philosophy of education and urban education. Kretz Ian Kretz is an undergraduate student at Rice University majoring in physics and mathematics. Magnetic materials are those which are affected by magnetic field and non magnetic materials are those which are not affected or slightly affected by magnetic field. Unlike lines of electric flux, which radiate from and terminate at the charged surfaces, lines of magnetic flux exist all the way through the magnet. The field pattern produced by a current flowing through a straight conductor is illustrated in figures below.
This course will explain the basis of the electrical, optical, and magnetic properties of materials including semiconductors, metals, organics and insulators, and will show how devices are built to take advantage of those properties.

Electric current and resistance are introduced, and then the course moves to the magnetic field, Ampere's Law, and induction. A magnetic field is defined as the space surrounding a permanent magnet or electromagnet where the electric field is felt by other magnet or magnetic material. When a unit magnetic pole is placed inside a magnetic field, it will experience both repulsive and attractive force, from similar and opposite poles of the magnet, respectively. This unit of flux density is named as Tesla after the name of famous American scientist, Nikola Tesla. It is illustrated with a wide range of devices, placing a strong emphasis on new and emerging technologies. PHYS 102x consists of ~1.5 hours of weekly video lectures, weekly online homework questions, and two online exams.

The course runs 10 weeks, but during the two exam weeks there will be no new topics or homework assignments.
Hafner is currently an Associate Professor of Physics and Astronomy and of Chemistry at Rice, as well as an Associate Editor of ACS Nano. Some of the non magnetic materials exhibit very slight magnetic effect but it is extremely difficult to detect. The path through which the unit pole travels in the magnetic field is referred as magnetic lines of force. The field of these magnets are also not everlasting, it will be loosened over a period of time. The direction of field can also be reversed by reversing the direction of current flowing through the conductor.
He has taught freshman and sophomore physics at Rice for the past eight years, and is a member of Rice's Center for Teaching Excellence. There are numbers of magnetic lines of force in a magnetic field, and these lines of force are collectively called magnetic flux.
Because of these many advantages, electromagnets are more suitably used in the field of engineering. On the other hand, all the materials which exhibit magnetic effect strongly are referred as magnetic materials or ferromagnetic materials.
Because of these many disadvantages, the applications of permanent magnet in the field of engineering are quite limited.
