Neodymium Magnets

Mighty, Amazing and Mighty Amazing!

 

 

 

 

 

 

Neodymium magnet in a copper pipe video

Drop a neodymium magnet through a copper pipe and it slows down.  

What is going on here?  

When the powerful neodymium magnet travels through this heavy copper pipe it slows down as though the force of gravity has been reduced.  

Is this an example of anti-gravity?

Perhaps the neodymium magnet is slowed by magnetic attraction to the copper pipe?  

No, the magnet is not attracted to copper.  We can see that in the first few moments of the video.

If it were a steel pipe, the neodymium magnet would immediately stick to the pipe.

So if it’s not magnetic attraction, what is going on?  Magnetism is apparently involved but how?

What’s your hypothesis?

If you would like to conduct your own experiments or demonstrations, cheap neodymium magnets are available.

You can buy one of these amazing neodymium magnets on Amazon by clicking on the photo below.

  • Neodymium Iron Boron (NDFeB) Rare Earth Magnets
  • Super Powerful Neodymium Magnets, many times stronger than ceramic or iron magnets
  • Pull Force is 91 lbs, strong enough to require extreme care
  • Highest performance, Low Price
  • Size: 1″ diameter x 1″ thick
  • Quantity: package includes two magnets

Neodymium is a “rare earth.”  Rare earth magnets are extremely powerful and useful for electronics applications.  

Imagine tying a disk like the ones below to a string?  You could pick up one-pound metal objects “fishing” down a non-magnetic pipe.  What happens when you put them on a wooden dowel?  A copper dowel or heavy wire?  I have no idea!

Neodymium Rare Earth Magnet Rings

  • 3/8″ Outer Diameter, 1/8 ” Inner Diameter, 1/16″ Thick
  • Pack of 12
  • 1.2 pounds of pull perpendicular to a flat, ideal holding surface.

 Any theories on why a neodymium magnet would slow down as it falls through a copper pipe?  

Would the same thing happen with an aluminum pipe?  

What if the pipe had thinner walls?  Please share your scientific theories or whether you share my conviction that magnets are magic!
