 13.1 Magnetic Force and Fields

Biomagnetism  Page (475, #5 )

Read about biomagnetism in this article posted on a personal Web site. This site details what biomagnetism is and provides examples of animals that use biomagnetism.

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

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

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

The Canadian Health Services Research. The 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

Physics Central -- Superconductors   Page (505, #24 )

The site explains what superconductors are and their applications, including Maglev Trains, MRI Scans, and Particle Accelerators. An excellent source of information on the applications of electromagnets.

Uses of Electromagnets  Page (505, #24 )

This site from Wikibooks details two uses of electromagnets--the electric bell and the loudspeaker.
