You should know that there are a large number of tutorials online for ways to make a handheld EMP (electromagnetic pulse). They will disrupt electronic devices in your vicinity and would be very useful if masked men approach you and try to photograph you with a potentially illegal biometric collection application. If made correctly they are harmless to people, and if made incorrectly they are most likely harmful to the operator. It is a non-violent defense device.
Bullets are lead. How exactly does one expect an EMP to have any effect on them…?
Correct.
Just a strong enough EMP would solve it. Not a scientist but guess is that a magnetic pulse strong enough to deflect bullets would do something to your atoms as well
It’s a wishful thinking button. Have to hope that they miss.
