Attraction and Repulsion: The Magic of Magnets
Conditional Remix & Share Permitted
CC BY-NC-SA
Rating
0.0 stars

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.

In this activity related to magnetism and electricity, learners create a magnetic field that's stronger than the Earth's magnetic field. Learners use electric currents that are stronger than the field of the Earth to move a compass needle. The assembly is made using a lantern battery, heavy wire, a Tinkertoy㢠set, and poster board and utilizes 4-6 small compasses and 2 electrical lead wires.

Eddy Currents

Rating
0.0 stars

In this activity related to magnetism and electricity, learners discover that a magnet falls more slowly through a metallic tube than it does through a nonmetallic tube. Use this activity to illustrate how eddy currents in an electrical conductor create a magnetic field that exerts an opposing force on the falling magnet, which makes it fall at a slower rate. This activity guide also includes demonstration instructions involving two thick, flat pieces of aluminum to illustrate the same principle.

This course is a three-part series which explains the basis of the electrical, optical, and magnetic properties of materials including semiconductors, metals, organics, and insulators. We will show how devices are built to take advantage of these properties. This is illustrated with a wide range of devices, placing a strong emphasis on new and emerging technologies.
The first part of the course covers electronic materials and devices, including diodes, bipolar junction transistors, MOSFETs, and semiconductor properties. The second part covers optical materials and devices, including photodetectors, solar cells (photovoltaics), displays, light emitting diodes, lasers, optical fibers, optical communications, and photonic devices. The final part of the series covers magnetic materials and devices, including magnetic data storage, motors, transformers, and spintronics.
This course was organized as a three-part series on MITx by MIT’s Department of Materials Science and Engineering and is now archived on the Open Learning Library, which is free to use. You have the option to sign up and enroll in each modules if you want to track your progress, or you can view and use all the materials without enrolling.
