GEOLOGY

Detailed explanation-1: -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.

Detailed explanation-2: -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-3: -Electromagnets can be created by wrapping a wire around an iron nail and running current through the wire. The electric field in the wire coil creates a magnetic field around the nail. In some cases, the nail will remain magnetised even when removed from within the wire coil.

Detailed explanation-4: -Q. What would increase the strength of an electromagnet? Increasing the amount of current flowing through the wire.

Detailed explanation-5: -Solution: Strength of electromagnet: The strength of the electromagnet net can be increased: By increasing the current in the coil. By increasing the total number of turns of the coil.
