S&T Feb 2020 has an article about micrometeorites.

 In 2003 when I stayed in an Astro B&B in New Zealand,

(Southern Heavens Homestead-no longer in business)

the owner collected the micrometeorites

by drawing a large magnet across the bottom of his swimming pool.

This thread (https://www.cloudyni...orites-at-home/) contains some fascinating information on this very subject.

Another source are the rain gutters around the house. They fall on the roof and get washed down and hopefully remain in the gutter.

 

Over here in the North East and West it is said a good chance of finding a large meteorite is in the old dry stone walls. People didn't know what they were (nor care I guess) and if they found a nice heavy "stone" it went in to the dry stone wall.

There are any number of sources that result in particles collected from roofs, or pools, being attracted to a magnet. The vast majority are not meteoritic in origin. For a better and more definitive discussion, check into Jon Larsen's book and research. The links to his work don't appear to be loading properly, but a Google search will take you there.

Great point Lee.  I myself have proven some of the magnetic material found in rain gutters are from the roof shingles....
