Eletromagnets question, would making the coils closer togeather with thinner wire make the magnetic field stronger?

If the current flowing through the coil remains the same, then yes. The field inside the coil is proportional to the number of loops per unit length of the coil. If you increase this loop density, you increase the field strength.
