In collision based computing, accurate timing is essential. As signals propagate through the system they must remain in sync, or the operation of many logic gates fails. In order to address this, an innovative system of electromagnets (EMs) was implemented. This was possible due to the generation of novel LMs with a mix of ultra-high density polyethylene (UHDPE) (Sigma-Aldrich, 3-6 × 10 6 g mol -1 , grain size approximately 100 µm) and nickel (GoodFellow Metals, 99.8 %, grain size 4 µm to 7 µm). A typical Ni/UHDPE coating was 2.5 mg. The use of UHDPE provides strength and durability, and the inclusion of ferromagnetic nickel allows for a versatile magnetic LM.
