How would I bulid a device around a door to destroy magnetically stored data?

 

 

Just a really big ring-shaped electromagnet.

 

 

Purely hypothetically speacking.

Sounds good to me... having a nice gas fire there would also work, not very good for humans though.... Where as a relatively high B filed (a few Teslas) will have a very small effect on humans...

Ok for a electromagnet around a 80 inch by 36 inch door (203.2 cm by 91.44 cm) How much copper wire would I need to get to make the strongest magnetic field possible?

 

Thanks
