Define a magnetic field as the designated region around a magnet where an observable force acts directly on another magnet or a viable magnetic material (e.g., iron, steel, cobalt, and nickel).
Recognize that the active force between a magnet and a magnetic material is unyieldingly one of attraction.
Understand that magnetic field strength is heavily dependent on the distance extending from the magnet and strictly peaks at the poles.
Determine the direction of any magnetic field point by referencing the direction of the theoretical force acting on a north pole placed at that point (field lines always orient north to south).
Explain how a traditional magnetic compass utilizes an internalized small bar magnet that actively aligns pointing towards the overarching Earth's magnetic field.
Describe the practical methodology required to properly plot the magnetic field pattern surrounding a magnet using a compass.
Draw a comprehensive magnetic field pattern of a bar magnet visually demonstrating distinct shifts in field strength and vector direction.
Explain how the predictable behavior of a magnetic compass inherently provides scientific evidence verifying that the Earth's core must actively be magnetic.
