The neutron's quarks include one up and two downs, so it is total electric charge is zero. The neutron may be electrically neutral, but don’t let that fool you, it still interacts with the electromagnetic field.","thumbnail_url":"https://img.transistorcdn.com/ms0DEdWGHxRFV-iwboilxOVVMywvTeQXj3rWZPK1by4/rs:fill:0:0:1/w:400/h:400/q:60/mb:500000/aHR0cHM6Ly9pbWct/dXBsb2FkLXByb2R1/Y3Rpb24udHJhbnNp/c3Rvci5mbS9zaG93/LzE3MzEwLzE2MDk3/ODE1MDAtYXJ0d29y/ay5qcGc.webp","thumbnail_width":300,"thumbnail_height":300}
