GEOLOGY

Detailed explanation-1: -The strength of an electromagnet can be increased by increasing the number of loops of wire around the iron core and by increasing the current or voltage.

Detailed explanation-2: -There are three ways to strengthen an electromagnet: increasing current. increasing the number of turns of the coil. adding an iron core.

Detailed explanation-3: -The strength of an electromagnet changes depending on the size of the attached battery. A higher voltage battery will produce a larger current through the same wire. This, in turn, results in a stronger magnet.

Detailed explanation-4: -The number of turns as well as the magnitude of current decide the intensity of magnetic field produced. More number of turns as well as inreasing the current flowing through the coil, increases the strength of the electromagnet.

Detailed explanation-5: -There are two methods by which we can increase strength of magnetic field are: 1) By increasing the number of turns of wire in the coil. 2) By increasing the current flowing the coil.
