We'll explore electric current and magnetism, making electromagnets, electric motors, speakers, and more.
Electromagnet., wind wire onto a bolt to pick up paper clips.
Circles of magnetism, Surround a vertical wire with compasses. Notice the magnetic field when electric current flows in the wire.
Stripped Down Motor, Make a current carrying coil of wire rotate in a magnetic field.
Ammeter, measure electric current.
Speakers, turn electric current into motion and thus sound.
