I really liked this design idea , its more like a mama hen in design and so I showed it to my husband who is a certified Master A technician for the last 30 years , and he says this type of heating pad over wire set up creates a magnetic field, and that can mess with the chicks in some way..? he says that this type of magnetic field can create something very similar in nature to an MRI...?
If you are living under power lines the measurable radius of the magnetic field is ...
Maximum values may be lower for some utilities
Distribution lines1 to 80 milligauss under the line
Transmission lines1 to 300 milligauss edge of right of way
All electricity carries with it a magnetic field unless its shielded. Any UL device that is sold in the United states is tested and approved for safety. Which I believe includes the amount of electromagnetic field it generates

Interaction with the wires will create a magnetic field but it will not create one greater than the pad itself. How many miligauss does he estimate it will create?

I worked in the electronics packaging field before retiring... meaning building boxes around computers.... LOL. But I am a gear head not a sparky...
