How does the number of coil turns affect magnetomotive force?

In the context of an electromagnet, the magnetomotive force ($F$ or $F_m$) is defined as the product of the total number of turns in the coil ($N$) and the current ($i$) flowing through it, expressed as $F=Ni$.1

Because the magnetomotive force is directly proportional to the number of turns, increasing the number of turns in the coil—while keeping the current constant—will result in a proportional increase in the magnetomotive force generated by the device. This force is responsible for generating the magnetic field that produces magnetic flux within the magnetic circuit.1
