One day I am going to acquire an enormous directional electromagnet, like you get on the end of cranes in scrapyards, except much more powerful.
I will then roll up outside one of those dismal rock/metal nightclubs at kicking out time, power it up and cackle dementedly as the genitals of hundreds of e.dgy-lite morons and moronettes explode in a red mist.
The collected metalwork I shall have cast into a helmet.

>>1-kun, it is pretty much impossible to achieve such magnetic field strengths at the distances you specify.

You have no edge in this game. You are all flat surface placed normal to the incident event.
