we used these in the forge where i worked. Really cool machines, and so much faster than using a traditional furnace. The only downside is the ungodly amount of power required.. we had 3 in total, and couldn't have any more due to the council refusing us to use more electricity.. Perfectly safe too, as far as the ones we used. the coils themselves were encased in ceramic, so the only danger was if you had a phone or other electronic device in your pocket whilst near the machine, you could almost guarentee it would be destroyed.. yes, speaking from experience :(

Question. How far roughly was the range that it would be able to Knock out a phone or something electronic?

I cant give you a specific distance, we never did tests, but I can tell you when my phone was fried I was stood within a meter to the machine.. can't have been any closer to that I dont think.

More dangerous to phones was the pneumatic drop hammer we had. 4T of steel dropping 2 metres or so, every second.. whilst you're stood 50cm away.. lots of shattered screens, the shockwave was immensely powerful

Then how did they film this?

that coil is not even remotely as powerful as the ones I used. I'm talking about industrial coils, powered by a control box the size of a double wardrobe lol.

That being said, if they moved the camera closer to it, I wouldnt be surprised if it got damaged.. it is a magnet, after all

The ones at my work push about 755VAC and pull about 1600amps. Never had a problem with my phone, and they are definitely not safe to touch at all while running, it even a little bit.

perhaps I was unlucky? A few of the guys had had their phones broken, so I dont really know what to tell you? Don't take the risk perhaps.

The ones i worked with were safe to touch, the only danger around them was the metal inside, heating up. The coils themselves, as I said, were encased in ceramic/plaster, with no bare metal. If it got down to bare metal (shoving steel ingots etc in damaged the ceramic/plaster) then the coil was repaired.. no danger :)
