 I am trying to block a 240 Volt 50Hz electromagnetic field.
 While trying different materials i found that copper reduces the electromagnetic field from 5mG το 2,5mG.
 
 Is Copper an effective material to block 240Volt 50Hz electromagnetic field?
 
 Is that reading correct?

Also, at these frequencies, shielding is not really a matter of reflection and absorption. It's more a matter of locally redirecting the fields.
