Flashcards

Magnetic Force

A force that can attract or repel objects at a distance due to the interaction of magnetic fields.

Like Poles

Magnetic poles that repel each other, such as North-North or South-South.

Opposite Poles

Magnetic poles that attract each other, such as North-South.

Magnetic Field

The area around a magnet where the magnetic force is exerted.

Study Notes

Magnetic Field Review

A magnetic force can pull (attract) or push (repel) objects from a distance.
Opposite magnetic poles attract, and like poles repel.
The magnetic field patterns between attracting and repelling magnets differ.
A magnetic force can convert stored magnetic energy to motion (kinetic energy).
Energy used to move a magnet against a magnetic force is stored as potential energy in the magnetic field.
Models of magnetic systems help understand force and energy relationships.
Moving a magnet against a stronger magnetic field results in more energy transfer.
Magnetic forces are stronger closer to a magnet.

Key Concepts for Systems

Systems involve various parts (magnets) whose interactions affect potential and kinetic energy.
Identify and describe potential energy within a magnetic system.
Identify and describe kinetic energy within a magnetic system.
Illustrate magnetic fields with drawings.
