What steps should be taken to increase the amount of current produce a generator​

The maximum potential difference or current can be increased by:

1. increasing the rate of rotation.

2. increasing the strength of the magnetic field.

3. increasing the number of turns on the coil.

It depends. Remember that power is voltage x current. So, do you have enough voltage? You can buy modules that increase and decrease voltage. That is one possibility. Please check all safety guidelines of the generator before doing this. modifying the voltage to a generator without making sure it can take more voltage can be counterproductive

what experimental evidence led scientists to change from the previous model to this one?

a few of the positive particles aimed at a gold foil seemed to bounce back.

the colors of light emitted from heated atoms had very specific energies.

experiments with water vapor showed that elements combine in specific proportions.

cathode rays were bent in the same way whenever a magnet was brought near them.

that would be because of both gravity and friction. so     c
