Connections to Science: Electric Motors

Duration: 03:54

Join Abby from IPTV as she helps explain some of the interesting characteristics of electric motors and magnetism.

Iowa Common Core Science Standards

Physical Science:

Essential Concept and/or Skill: Understand and apply knowledge of sound, light, electricity, magnetism, and heat.

Essential Concept and/or Skill: Understand and apply knowledge of motions and forces.
Principles that underlie the concept and/or skill include but are not limited to:

Electric and Magnetic Forces
The electric force is a universal force that exists between any two charged objects. Opposite charges attract, while like charges repel. The strength of the force is proportional to the charges, and, as with gravitation, inversely proportional to the square of the distance between them.

Electricity and magnetism are two aspects of a single electromagnetic force. Moving electric charges produce magnetic forces, and moving magnets produce electric forces. These effects help students understand electric motors and generators.
