13.1 Magnetic Force and Fields

4-D Neuroimaging Page (475, #5 )

4-D Neuroimaging company website. The site describes various devices used in medical imaging. The link to Doctors Discuss MEG highlights new advancements in technology. Requires QickTime player to view.

Proximate Cause Page (475, #5 )

Dr. Chris Evans of McQuarrie University in Australia has provided these notes describing environmental/physiological causes of animal behaviour. The notes include a description of experiments of electroreception in sharks and magnetic sense in pigeons. The summaries are clear and concise.

Animal Behaviour Page (475, #5 )

A faculty page on the National-Louis University server with further information on many different aspects of animal behaviour. The site includes a discussion of Magnetic Calibration and Magnetic Sense in relation to birds, trout, etc.

Dalhousie University Research Areas Page (475, #5 )

From the Dalhousie University a page describing the current areas of research in biomagnetism - in particular, the measurement and analysis of magnetic and electric fields produced by the human body. The site has some interesting pictures and links to international biomagnetism Web sites.

13.4 The Magnetic Field of A Coil or Soleoid

The Real Levitation Page (489, #10 )

The University of Nijmegen faculty of Science Mathematics and Computing Science has an excellent site on diamagnetic levitation. This site includes theory, movies and photographs with detailed explanations of the concepts. Windows Media Player is required to view the videos.

Magnetic Levitation and 3D Imaging Page (489, #10 )

Martin Simon of the UCLA Physics Department describes diamagnetic "Levitation and levitating a magnet with fingers". Click on the various links to see detailed explanations of the phenomenon. The site includes a link to a Nature article on Magnetic Levitation at your fingertips (within the text). Another link leads to a website called "The Frog that Learned to Fly" (click on "suspension of living things such as frogs") which has Window's Media movies on different levitating objects - this site has both a complicated and a simple explanation as to what is happening.

Paramagnetic Oxygen Analysis Page (489, #10 )

From Servomex, a company dealing with paramagnetic technology, a description of the various products they make and how they work. See especially "Technology", then "Paramagnetic" for information on a Paramagnetic Torque balance, complete with illustrated steps on how it works.

13.6 Applications of the Motor Principle

The Coalition for Biomedical and Health Research Page (501, #3 )

The Coalition for Biomedical and Health Research. This site provides extensive information about research related issues in the biomedical field. The site contains sections on Research Funding including Quick Facts and a pie chart on the Gross expenditure on R & D in the Health Field in 1987 vs 1998. It also has a Research Awareness Section (which includes "Medical Advances due to Research" and "Awards and Recognition" sections) and current news.

National Health Research and Development Program Page (501, #3 )

The Canadian Health Services ResearchThe site contains extensive information on the granting process for projects. Exploring the site by clicking on the menus leads to different departments within Health Canada each of which monitors different research fields.

CIHR - Applications and Awards Page (501, #3 )

The Canadian Institutes of Health Research a government of Canada funding agency has this page of information on funding from individual Canadian institutes such as Institute of Aboriginal Peoples' Health, Institute of Cancer Research, Institute of Circulatory and Respiratory Health, Institute of Gender and Health Institute of Genetics, etc. This site gives an idea of the scope of research projects that are being funded.

Chapter 13 Review

Argonne Builds a Tradition of World Class Superconducting Magnets Page (505, #24 )
