There are two main factors that increase the magnetic field of an electromagnet:
1) Increasing the current flow: The strength of the magnetic field produced by an electromagnet is directly proportional to the amount of electric current flowing through it. Therefore, increasing the current flowing through the electromagnet will increase the strength of its magnetic field.
2) Increasing the number of turns in the coil: An electromagnet consists of a coil of wire, and the magnetic field generated by each turn of the coil adds up to produce the overall magnetic field of the electromagnet. Hence, increasing the number of turns in the coil will increase the strength of the magnetic field. This is because each turn of the coil contributes its own magnetic field, and when combined with the other turns, the overall magnetic field becomes stronger.
