    Up quarks have a charge of +2/3 (positive charge numerically 2/3 of an electron's charge). Down quarks have a charge of -1/3. Proton is 2 ups and a down as you say making 4/3 - 1/3 = 1. Neutron is 2 downs and an up, -2/3 + 2/3 = 0. Notice the the neutron has a magnetic moment - it will turn in a magnetic field - showing that it's components are charged even if the whole particle isn't.

    There's the positive half of a magnet inside of every proton.
