Build your home inside of a huge microwave and never worry about an emp ever again!
now a question?
If not shielded and a microwave would work as a faraday cage, does that means that microwaves will work after an emp?
The electronics that create the microwaves and the control circuits are outside the microwave shielded part of the oven, else they would be destroyed
So again, it comes down to distance from the blast point and the number of barriers between that determines how much EMP a household will receive
outside what comes through the electrical grid.
A microwave is not a perfect Faraday cage and some EMP will come through, but it will act as a barrier reducing the amount of EMP to the objects
Unplugging everything in your house if you have enough warning will reduce the amount of EMP those devices receive, but not all of it. The next
determination is how much metal surface area a device has or is connected to for EMP to pass through into the circuitry.
The design and hardiness of electronics has also changed since the mass testing occurred decades ago. Not due to EMP concerns , but other factors have
caused certain safeguards to be incorporated into electronics devices that may have the side effect of helping them survive and EMP blast.
There are multiple factors involved when it comes to EMP, as such no real practical answers. Sure we can talk about making your house a Faraday cage
or other such grandiose things, but in the end that is just impractical.
Devices close to ground zero will surely be destroyed, but as we get further away from the blast point, less damage will occur. The mathematics of
this are exponential and do not take into account barriers (natural or artificial).
I guess the only solid, practical answer is to be as far away from the blast point as possible, and have plenty of barriers between.
