AM car radio can pick up the waves from your cars electrical alternator as well, which can cause the static to rise and fall in pitch as you speed up and slow down.
Comment on What produced the old dead channel tv static audiovisuals on tvs?

You could also get hums and interference from other sufficiently strong EMF sources, like how AM radios can pick up the sound of transmission lines

Your mom (or dad) using an electric knife to cut a turkey on thanksgiving would do the same. It was wild.
