GEOLOGY

Detailed explanation-1: -The four main factors that affect the strength of an electromagnet are the loop count, the current, the wire size, and the presence of an iron core.

Detailed explanation-2: -The magnitude of the magnetic force between them depends on how much charge is in how much motion in each of the two objects and how far apart they are. The direction of the force depends on the relative directions of motion of the charge in each case.

Detailed explanation-3: -The answer is “all of these affect the strength of a magnet” The proximity to the object, the size of the object, the material of the object it is sticking to, and the temperature of the object all affect magnetic pull. Magnetism is the force by which objects are attracted to or repelled by other objects.

Detailed explanation-4: -The intensity of the magnetic field depends upon the number of magnetic field lines passing through a unit area. It also means, closer the magnetic lines of force, stronger the intensity of the magnetic field.

Detailed explanation-5: -The number of turns of wire wound around the coil, and. The amount of current flowing through the wire.
