Electrical transformers change the voltage of electricity coming from a power source to the proper voltage needed for an outlet (such as a home, business, etc.). They do so by using an iron core wrapped in electrical wire to create a magnetic field which can convert the electricity. This conductor’s surrounding magnetic field is called a magnetizing force.
Substances placed near a magnetizing force take on magnetic properties. The amount of magnetism induced into a body by a magnetizing force is called flux density. “The intensity of the flux density is affected by the intensity of the magnetizing force, the qualities of the substance, and by the intervening media between the systems.”
