Answer:There is no image but I hope this helps We like to represent this force effect of a magnet on iron-like objects with a concept called magnetic field. The concept of field can be best understood if we remember the gravitational force of Earth on object near it. ... represent this gravitational force effect with lines starting from Earth and radially diverging away to infinity.
Explanation:
sorry if this does not help.
