Magnetic materials can attract or repel each other based on their polar orientation — positive and negative ends attract each other, while two positives or two negatives repel. When an electromagnetic signal like a radio wave passes through such materials, a magnetic material acts like a gatekeeper, letting in the signals that are desired but keeping out others. They can also amplify the signal or dampen the speed and strength of the signals.
