Detailed explanation-1: -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-2: -A magnet’s strength is not only determined by its size, but also by the material of which the magnet is made and the number of “tiny magnets” lined up in the magnet. A larger magnet will have a stronger magnetic field than a smaller mag-net made of the same material.

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: -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.
