Study Notes

Magnetic Field Review

A magnetic force can pull objects together (attract) or push them apart (repel).
Like magnetic poles repel each other; opposite poles attract.
The magnetic field patterns differ between attracting and repelling magnets.
Magnetic forces can change potential energy into kinetic energy.
Potential energy is stored when a magnet is moved against a magnetic force.
Studying magnetic systems and their components helps understand force-energy relationships.
Moving a magnet against a stronger magnetic force transfers more energy to the field.
Magnetic force strength decreases further from the magnet.
Students should describe systems, including potential and kinetic energy within them.
Students should draw magnetic fields, determining potential and kinetic energy.
