Review on Stainless Steel Round Magnets by MagNetSol by Dee Fadaifar

Great for Warhammer 40k. They are very powerful and are great for replacing various weapons for tournaments. You can even pick them up with magnetized cannons/weapons. You can even use them to make units multifunctional; For example, if you just buy a bike and change the head or torso, you have the option to field a Librarian, Elder, Captain, or Chaplain without having to buy bikes for all of them.
