Answer:

  • increase the field strength
  • increase the current
  • decrease the moment of inertia of the coil

Explanation:

The rotation speed depends on the force applied to the coil, and on the mass (moment of inertia) of the coil. The force can be increased by ...

  increasing the magnetic field strength

  increasing the coil current

And the moment of inertia can be decreased by ...

  making the coil lighter

  making the coil more compact.

Any of these changes will increase the rotation speed.
