The idea is this: There are a great many neutrons in a neutron star and some of these undergo decay. This produces mostly (only?) left-spin electrons. This excess will move in the direction of magnetic flux, inducing a current.

This seems reasonable to me. Then in a neutron star core there will be a current flowing wherever there is sufficient magnetic flux. This is what interests me. Does that seem right?

I also wonder about the magnitude of this current.

(He goes further and proposes things that will happen if the star has no significant electron-absorbing crust, but this case is not in my interest.)
