Mississippi Science PHY.5.7
The Standard
- PHY.5
- Students will investigate the key components of electricity and magnetism.
Analyze and communicate the relationship between magnetic fields and electrical current by induction, generators, and electric motors (e.g., microphones, speakers, generators, and motors) using Ampere's and Faraday's laws.

What This Standard Means
What Students Need to Do
- Students show how electric current creates a magnetic field and how changing magnetic flux produces voltage. They use Ampere's and Faraday's laws to explain generators and motors. They trace motion, current, and magnetic fields in a speaker or microphone.
What Mastery Looks Like
- Students predict no induced voltage when a magnet stops beside a coil and a reversed meter reading when it moves the other way. They connect higher current to a stronger magnetic field and faster flux change to higher induced voltage. They explain that a generator turns motion into electricity, while a motor turns electricity into motion.
Common Misconceptions
- Students often expect a stationary magnet beside a coil to keep making current. They may swap the roles of motors and generators, or think induced voltage means current flows even when the circuit is open.
How to Assess It
- Draw a north pole moving into a coil connected to a meter. Ask students to predict what the meter shows when the magnet stops, then moves back out, and to explain why.

Ways to Teach It
Connect a wire coil to a sensitive voltmeter, move a bar magnet in and out, and record the sign and size of each reading.
Ask partners: Why does turning a generator light a bulb, while sending current through a motor turns its shaft?
Play a prediction game with diagrams of a magnet entering, leaving, or stopping beside a coil; score explanations of voltage size and direction.
Show diagrams of a bicycle dynamo powering a lamp and a speaker; have students label where motion produces current and where current produces motion.
