If you set up a system of blocks where there are scarlet neodynium blocks and any block that is not magnetic, you get flying anvils. I took screenshots using modrinth, so it naturally deleted them all, but I can show you a system of x and + where + is neodynium and x is "other block" (The c is where the anvil goes. Also, the "." is just because github likes to correct multiple spaces.)

. . x
x + x
. . c x
. . . .x +
