There's a very big difference between EM interference and an EM pulse. One is the by-product of all digital electronics and one is a device specifically designed to induce enough current on a circuit board/IC/etc to damage it.
That said, based on the size of that thing in the photo I suspect it wouldn't damage anything!
- jacquesm 10y agoThe biggest difference is the fieldstrength of the primary field used to induce a voltage in the target, the same basic principles apply. It takes a (much) higher fieldstrength to induce voltages that will destroy electronics than what's required to flip the occasional bit without damage. Lightning can cause EMP like effects by inducing voltage in conductors not directly hit by the lightning.
- bigiain 10y agoI vividly remember riding a motorcycle next to a lake, when a lightning strike hit the lake maybe 20-30m from where I was. The bike's engine died briefly (maybe 0.5 or 1 sec) then came good again - I'm pretty sure it was the fairly simple electronics driving the ignition getting "zapped". (This was a 1991-vintage bike - its modern enough that it uses hall sensors not points, but the electronics driving the ignition and the advance curves might even be analog instead of microcontroller-driven.)
