Hero, could you please explain to us what this has to do with the original posters question? Wait for their response before you judge them on previous posts that have nothing to do with them.
The number of users that come here with poor communication/language skills are much greater than those of that are actually stupid =)
uh its for a science project. I wanted to make an emp generator. but now i m more interested in what eric said. that is detecting cracks in metals using emp.
well jim for starters to design a system that can negate the effects caused by emp u must study a practical model of an emp generator. other than that shock waves can be used to destroy kidney stones. you can use them to disable vehicles. they can be used in security systems. my purpose well i wish to first study the emp generator and write a short report/thesis on its effects
There is absolutely nothing whatsoever fictional about an EMP Nigel, they're not just practical =) Big difference.
Explosively pumped flux compression generator - Wikipedia, the free encyclopedia
would be one example of a non nuclear EMP generator. Main problem being the explosive used to create it is typically more effective than the EMP it generates in the first place. They're also relatively easy to defend against, grounded metal housings and appropriate TVS suppression on incoming/outgoing lines will protect against them except at extremely close distance, which again if you have close distance you might as well just blow it up normally, far more effective.
wal.ee I'm not sure what use they would have in stopping a vehicle, or in security systems, all systems I know of that exist that can do that are nothing more than high voltage pulses such as a taser or the vehicle disabling ones are nothing more than high voltage arcs designed to fry the electrical system, a far cry from the classical description of an EMP.
