Learning Objectives

-Connect the ancient history of magnetism with modern understanding that magnetism is rooted in electron movement.

-Explain the right-hand rule for determining the direction of magnetic force on a moving charge.

-Calculate the magnetic force acting on a moving charge.


Note-Taking Guide and Questions to Consider
Practice Problems
Exploring Magnets & Magnetic Fields Lab


electromagnetism - the interaction of electric currents or fields with magnetic fields.

magnetism - an effect produced by the motion of electric charge, resulting in attractive and repulsive forces between objects.

magnetic field (B) - a region around a magnetic material or a moving electric charge within which the force of magnetism acts.

magnetic force (FB) - a push or a pull exerted on a moving charge that is equal to the magnitude of that charge multiplied by the velocity of the charge multiplied by the strength of the magnetic field where the charge is located.

Georgia Standards of Excellence

SP5Obtain, evaluate, and communicate information about electrical and magnetic force interactions.


Plan and carry out investigations to clarify the relationship between electric currents and magnetic fields.
(Clarification statement: This includes coils and their importance in the design of motors and generators.)

SPS10Obtain, evaluate, and communicate information to explain the properties of and relationships between electricity and magnetism.

SPS10.cPlan and carry out investigations to determine the relationship between magnetism and the movement of electrical charge. (Clarification statement: Investigations could include electromagnets, simple motors, and generators.)

S8P5Obtain, evaluate, and communicate information about the phenomena of gravity, electricity, and magnetism as major forces acting in nature.

S8P5.aConstruct an argument using evidence to support the claim that fields (i.e., magnetic fields, gravitational fields, and electric fields) exist between objects exerting forces on each other even when the objects are not in contact.
