the region surrounding a magnet in which magnetic force is exerted is called a magnetic field.the magnetic field has both magnitude as well as direction. therefore it is a vector quantity. the strength of magnetic field is measured in a unit called tesla(T) the direction of magnetic field at a point is the direction of a unit north pole placed at that point.
the electromagnet made by winding 100 turns will attract more pins than electromagnet made by winding 50 turns as the larger number of turns in the solenoid,greater will be the magnetism produced.
