I use NIB magnets in many of my projects. NIB stands for Neodymium-Iron-Boron and are the most powerful in common use.

SuperHero Element time. THOR: An essential part of his hammer is of course, Thorium.
For ordinary mortals, Thorium 2% is added to tungsten welding rods. Here it has a count of 564 CPM (counts per minute). Background radiation is about 50 CPM.

A magnetic field viewer recording 3 different axes of a specific value of magnetic flux.
This is a wish list of magnetism projects in no particular order. Some small and interesting to me and others to try things I have not seen on the net before.

This specimen of Lodestone is only a couple of cm long. It is a magnetic rock called magnetite used as one of the earliest compasses. Here it is shown with some iron filings attracted to to it. This also shows the areas of greatest magnetisation.

Singing magnets are magnets that make a peculiar sound when they crash together under magnetic attraction. They are ovoid magnets can be bought in novelty stores and eBay for less than $10. Also known as rattlesnake or buzz magnets. They might make an interesting amusement as a present for the geek in your life.

Iron filings, magnetic viewing film or ferrofluid can all make magnetic field lines visible. Isolated readings can be also taken with gauss meters. Sure there are some nice computer graphics of predicted fields and the earth’s fields. But what about around other places such as large irregular magnets or even the earth’s magnetic field lines in your back yard for example?

A polonium 210 source in a needle is used for Alpha particle experiments such as cloud chambers. The activity is less than 0.1 uCurie and the half life is 138 days. I had better get on and do stuff before it goes away.
