When gas turbines are used in extended-range electric vehicles, like those planned by Land-Rover / Range-Rover in conjunction with Bladon, or by Jaguar also in partnership with Bladon, the very poor throttling response ( their high moment of rotational inertia ) does not matter, because the gas turbine, which may be spinning at 100, 000 rpm, is not directly, mechanically connected to the wheels.
The moment of inertia is the measure of resistance to torque applied on a spinning object ( i. e. the higher the moment of inertia, the slower it will spin when a given force is applied ).

( A spinning superconductor generates a magnetic field precisely aligned with the rotation axis – see London moment.
The above equation can be used for calculating a magnetic moment of any assembly of moving charges, such as a spinning charged solid, by substituting
This implies that a more massive assembly of charges spinning with the same angular momentum will have a proportionately weaker magnetic moment, compared to its lighter counterpart.
This can be understood with the following classical picture: if we imagine that the spin angular momentum is created by the electron mass spinning around some axis, the electric current that this rotation creates circulates in the opposite direction, because of the negative charge of the electron ; such current loops produce a magnetic moment which is antiparallel to the spin.
