Things the curious engineer in me does…

This is the old malfunctioning motor from my dishwasher. Those are some pretty hefty looking electromagnets!

I wondered how much copper there was coiled up on each bar.

Turns out, about 20g. Total of 180g of copper. The whole assembly weighs 410g.

Scrap copper is worth about £6.50/kg. So it’s not worth much. But it’s not worth nothing!
