Investigating Magnetic Fields
Plot the magnetic fields around permanent magnets
Use a plotting compass to map magnetic field lines around different magnet configurations
"Physics is the science of all the tremendously powerful invisibilities - of magnetism, electricity, gravity, light, sound, cosmic rays. Physics is the science of the mysteries of the universe."
Electromagnets
Explore how electric current creates magnetic fields
Investigate the factors that affect the strength of an electromagnet, including current, number of coils, and core material.
Motor Effect
Discover the force on a current-carrying conductor
Explore how a current-carrying wire in a magnetic field experiences a force. Investigate Fleming's left-hand rule and the factors affecting the force.
Electromagnetic Induction
Generate electricity from changing magnetic fields
Investigate how moving a magnet through a coil induces a voltage. Explore Faraday's law and the factors affecting induced EMF.
Transformers
Step up and step down voltage with coils
Explore how transformers use electromagnetic induction to change voltage. Investigate the relationship between turns ratio and voltage ratio.
