The earth magnetism is static, it doesn't change in practical terms(in a window of a second), neither periodic or not. To hear someone tell: this is like the earth magnetism, this is not radiation, is trying to fool people, I'm sorry but I feel very upset about it. If they use let's say 50Herzs, they are emiting photons, not in the visible range, but they are photons anyway, but they are not going to use 50Hz, they will use MHz and more, and that could resonate with proteins and destroy it. There are millions of proteins out there with different sizes, and shapes, to probe that one of them is destroyed by this this is impossible, but given the right size and the right frequency it will happen because everything has their characteristic frequency. The same way when you put water in the microwave oven it heats up because it has absorbed the energy and translated it to mechanical energy because of the characteristic frequency of the water. With lower frequencies than mw oven you are going to resonate with bigger structures than water, water is small compared with proteins that could be thousands or millions of times bigger.
