HI!
I want to detect a low frequency electromagnetic waves
with a coil. I read this is a good solution
Will Choosing a different core material
iron versus mu-metal make the antenna better?
Will a higher permitivity material (mu metal) make
the coil antenna better?
What shape is better spherical or solenoid?
