Fig. 1From: A new portable ELF Schumann resonance receiver: design and detailed analysis of the antenna and the analog front-endSingle induction coil geometry. Our induction coil architecture is depicted in such block diagram. The core mumetal material length (lcore) and diameter (dcore) as well as the length of the wire windings (lwinding) are also shown. We implement that induction coil antenna using copper wire (diameter-dwire) and making n turns of windings that cover 70–90% of the total core length. The total induction coil diameter is defined by the thickness of windings (t) and the core diameter (dcore), providing that the total number of turns should approximate to 40,000Back to article page
