Making Resistive Magnets – Links & Resources

Audio Slideshows

• Making Resistive Magnets
  A nine-minute audio slideshow that discusses and illustrates much of the material in this article.
• The World's Strongest Magnet
  A nine-minute audio slideshow on our world-record 45 tesla hybrid magnet, which combines the powers and advantages of both a superconducting magnet and a resistive magnet.
• How to Make an Electromagnet
  What do you get when you mix a battery, a bit of copper wire and a nail? One of the most important forces in science. Try it yourself and let the force be with you!
• Helix Stacking
  A brief slideshow demonstrating how magnet builders helix-stack one turn of a resistive magnet coil.
• Flat Stacking
  A brief slideshow demonstrating how magnet builders flat-stack one turn of a resistive magnet coil.

Interactive Java Tutorials

• Lorentz Force
  Learn the Lorentz force with the help of this tutorial, in which a wire fashioned into a pendulum moves inside a magnetic field.
• Parallel Wires
  A pair of parallel wires serves to illustrate a principle that French Scienist André-Marie Ampère was the first to comprehend, back in 1820.
• Deionization
  The magnets here at the lab can generate massive amounts of heat. To cool them off, we need massive amounts of water. But first, we have to take the ions out.
• Magnetic Field of a Solenoid
  You can create a stronger, more concentrated magnetic field by taking wire and forming it into a coil called a solenoid.

Resources for Non-scientists

• Making Superconducting Magnets
  Like most people, we'd rather pay less for electricity. Which is one reason (though not the only one) that we use and build superconducting magnets.
• What's a Resistive Magnet?
  As defined by a Mag Lab expert (audio file).
• What's a Bitter Plate?
  As defined by a Mag Lab expert (audio file).
• Meet the Magnets
  We’d like to introduce you to a few of the amazing magnets that make our facility so unique and make possible new discoveries in science.
• Magnets from Mini to Mighty: An Introduction for Non-scientists
  If your knowledge of magnets ends with posting a to-do list on the fridge, add this to the list: Learn more about magnets! You can start here with a straightforward rundown of different magnet types, uses and strengths, explained in a way that will help make the facts stick.
• Team Tesla: How We Keep the World's Most Powerful Magnets in Shape
  Our magnets are like world-class athletes – Team Tesla, if you will. They have an awful lot of power, but to stay in that kind of shape, they need to eat and drink – a lot.
• Francis Bitter and the Invention of the Bitter Plate
  Without Francis Bitter's contributions to magnet technology, the Magnet Lab as we know it would be very different – and it might not even exist.
