Neutrons are electrically neutral because of their internal composition of quarks, which are subatomic particles that carry fractional electric charges.12

A neutron is composed of three quarks: one up quark and two down quarks. These quarks possess the following charges:12
* Up quark: $+ 2 / 3$ of the elementary charge ( $e$ )12
* Down quark: $- 1 / 3$ of the elementary charge ( $e$ )12

When these charges are combined, the total net charge of the neutron is zero:
$(+ 2 / 3) + (- 1 / 3) + (- 1 / 3) = 0$

While the neutron has no net electric charge, it does possess a magnetic dipole moment, which indicates that it contains moving electric charges within its structure.1
