GEOLOGY

Detailed explanation-1: -Electromagnets are the formation of solenoids, i.e., a coil of wire is wrapped around a metal core made of iron. The coil is made of wire loops, and the more loops added, the stronger the magnetic field is and vice versa.

Detailed explanation-2: -The strength of the magnetic field around a solenoid can be increased by: increasing the number of turns on the coil. increasing the current.

Detailed explanation-3: -The more loops the coil has, the stronger the magnetic field, while the current is flowing.

Detailed explanation-4: -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-5: -When an electric current flows through a wire, a magnetic field is generated. The more coils there are, the stronger the magnetic field would be.
