    1. Science is wild basically the universe said free microwave but only if you understand Maxwell’s equations.

    2. They use this for hardening crankshafts in engines. First time I saw it was back in the 70’s at Longbridge Birmingham in the UK. I thought it was witchcraft.😂
      Valuable lesson though as I was a first year electrical apprentice at the time!
