increasing the number of turns in the coil of wire

Answer 1

The factor that would decrease the magnetic field strength of an electromagnet is:

increasing the distances between the turns of the coil.

This is because increasing the distance between the turns reduces the density of the magnetic field lines generated by the current flowing through the coil, leading to a weaker overall magnetic field. The other options provided (increasing the current or using a higher-voltage power source, using an iron core, and increasing the number of turns in the coil) all lead to an increase in the magnetic field strength.
