What effect does increasing the number of turns on the coil of an electromagnet have?

Increasing the number of turns on the coil of an electromagnet enhances its strength. This happens due to the principle that the magnetic field produced by an electromagnet is proportional to the number of coil turns and the current flowing through it. Each loop of wire contributes to the overall magnetic field, so more turns result in a stronger cumulative effect.

As the number of turns increases, the magnetic field lines become denser, leading to an increase in the strength of the magnet. This is why electromagnets are often designed with a larger number of turns to improve their effectiveness in applications that require a strong magnetic field, such as in electric motors or magnetic cranes.
