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: -We can say that, the strength of the electromagnet is directly proportional to the number of turns in the coil. If you double the number of turns, you double the strength of the electromagnet.

Detailed explanation-3: -You can add more coils on top of the first row, and this just adds more field strength. In technical terms, every coil of wire increases the “magnetic flux density” (strength) of your magnet. The magnetic field on the outside of the coil resembles a bar magnet.

Detailed explanation-4: -Number of turns in the coil: The strength of electromagnets rises with the number of coils. The magnetic fields help each other and become stronger if the loops curl in the same direction.

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.
