I rewound armatures for my slot cars as a teen. Field strength is a function of the number of turns or loops and the current. Start by using an ohmmeter to measure the resistance in each pole. Larger wire means less resistance but fewer turns. Cooling helps reduce resistance from heat in the wires. Match the field windings to the armature magnetic field strength. Look for old books in the library such as the Audel's series.
