Which Magnets to Buy

 Here's what to buy:

All round in shape except as noted.

Diameter x Thickness  (quantity)

1/8" x 1/16"  (100)

1/8" x 1/32" (100)

1/4" x 1/8" (40) these are very strong

1/4" x 1/16" (60)

1/2" x 1/16" (10)

You can also just stack thinner magnets.

Donut magnets can be slid onto flying stand rods for flying vehicles, most convenient.

1/4" x 1/4" with a 1/8" hole.

For heavy lifting you may need larger magnets

1" x 1/4" (6) these are the size where you could actually hurt yourself if they "jump" to another magnet and smash your fingers, they can also shatter into sharp shards.
