The magnets in Set 1 will attract, and the magnets in Set 2 will repel.

The magnets in Set 1 will repel, and the magnets in Set 2 will attract.

The magnets in Set 1 will not move, and the magnets in Set 2 will attract.

In both sets, the magnets will attract.

In a system of magnets, there is a repelling force with ____ poles.

south and south, north and north

Which is NOT what makes an electromagnet different from other magnets?

The magnetic force can be shut off.

The magnetic force strength can be changed.

Eli is holding two magnets close to each other. What will happen when he lets go?

The magnets will move away from each other because the magnetic force will push the magnets apart.

The magnets will not move because the magnets are not touching.

The magnets will move closer to each other because the magnetic force will pull the magnets together.

The magnets will move away from each other because the magnets are not touching.

Ramon puts two magnetic toy trains very close to each other on a track. What will happen next, and why?

The trains will move away from each other because the magnetic force will push the trains apart.

The trains will move closer to each other because the magnetic force will pull the trains together.

The trains will not move because the magnets are not touching

The trains will move away from each other because the magnets are not touching.

A spaceship is traveling through space. Suddenly, its speed increases. What can you say about the kinetic energy of the spaceship?

The kinetic energy increases as its speed increases.

The kinetic energy decreases as it is converted into speed.

The kinetic energy remains the same because speed and kinetic energy are not related.

There is no way to know what happens to the kinetic energy.

An engineer is investigating potential energy with two identical magnetic roller coaster cars on different sides of a center magnet that cannot move. To test her ideas, the engineer will move one car one space. Which movement will result in the largest increase in potential energy?

The potential energy increases because Magnet 2 moves against the magnetic force.

The potential energy does not change because the magnets in the system do not change.

The potential energy decreases because Magnet 2 moves against the magnetic force.

The potential energy decreases because Magnet 2 moves in the same direction as the magnetic force.

Based on the magnetic field line diagrams, what will happen next with these sets of magnets?

The magnets in Set 1 will attract, and the magnets in Set 2 will repel.

The magnets in Set 1 will attract, and the magnets in Set 2 will not move.

The magnets in Set 1 will repel, and the magnets in Set 2 will attract.

In both sets, the magnets will attract.

What is NOT a way to change the strength of the magnetic force an electromagnet can apply to another object?

Change the north pole and south pole of the electromagnet.

Change the amount of electric current on the electromagnet.

Change the amount of coils around the nail in the electromagnet.

Change the distance of the second object to the electromagnet.

About this resource

This quiz comprehensively assesses 8th grade students' understanding of magnetic fields, electromagnetic systems, and energy transformations. The questions require students to demonstrate mastery of fundamental magnetic concepts including attraction and repulsion between like and opposite poles, magnetic field line interpretation, and the unique properties of electromagnets. Students must apply their knowledge of magnetic forces acting at a distance, analyze magnetic field diagrams to predict magnet behavior, and understand how electromagnets differ from permanent magnets through their ability to be controlled, reversed, and adjusted in strength. The energy-related questions integrate kinetic and potential energy concepts within magnetic systems, requiring students to understand how energy transforms when magnetic objects move with or against magnetic forces. These problems demand both vocabulary mastery and conceptual reasoning about invisible forces and energy relationships. Created by Gina Ortiz, a Science teacher in US who teaches grade 8. This assessment serves as an excellent summative evaluation tool following a complete unit on magnetism and electromagnetic forces, though individual sections can function effectively as formative assessments throughout instruction. Teachers can deploy vocabulary questions as warm-up activities, use diagram interpretation problems for guided practice sessions, and assign energy transformation scenarios as homework to reinforce classroom learning. The quiz effectively measures student achievement of Next Generation Science Standards MS-PS2-5 (magnetic forces and fields) and MS-ETS1-4 (electromagnetic solutions), while also connecting to MS-PS3-2 regarding energy interactions within magnetic systems. The varied question formats accommodate different learning styles and provide comprehensive data about student understanding across multiple dimensions of magnetic field concepts.
