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 factors affecting the strength of a magnetic field at a point due to a straight current-carrying conductor are the magnitude of the electric current and the perpendicular distance between the point and the conductor.

Detailed explanation-3: -As we increase the current (amount of charge in motion) the field increases proportionally. As we move further away from the wire, the field we see drops off proportionally with the distance. This is described by Ampere’s law.

Detailed explanation-4: -increasing the number of turns on the coil. increasing the current. placing an iron core inside the solenoid.

Detailed explanation-5: -Increase the number of coil turns. Increase the current flowing through the coil. Wrap the coil tightly around the iron piece. Increase the current or voltage.
