Lesson 5: Electromagnetism and Induction

How can we use electricity to create a temporary magnet, and how can we control its strength?

What must happen to a magnetic field in order to successfully generate a current in a wire without a battery?

How do electric motors and generators use the exact same physics principles in reverse?

HS-PS2-5: Plan and conduct an investigation to provide evidence that an electric current can produce a magnetic field and that a changing magnetic field can produce an electric current.

HS-PS3-5: Develop and use a model of two objects interacting through electric or magnetic fields to illustrate the forces between objects and the changes in energy of the objects due to the interaction.

Unify electricity and magnetism by demonstrating that moving charges create magnetic fields, and changing magnetic fields induce electric current.

Wireless smartphone charging and green energy: When you place your phone on a wireless charging pad, an alternating current in the pad creates a changing magnetic field. This field passes into your phone, inducing a current in an internal coil that charges your battery—no plug required. This same principle allows wind turbines and hydroelectric dams to convert mechanical motion into the electricity that powers cities.
