Chapter 24: Magnetic Fields and Forces

These flashcards cover key concepts regarding magnetic fields and forces as discussed in Chapter 24.

Bar Magnet

A magnet that has a north and a south pole, and when flipped over, the south pole will attract the north pole of other magnets.

Magnetic Field

The area around a magnet where magnetic forces can be detected.

Right-Hand Rule

A method used to determine the direction of the magnetic field relative to the direction of current flow.

Compass

A device that shows the direction of magnetic north, used to determine the orientation of a magnetic field.

Solenoid

A coil of wire that generates a magnetic field when electric current passes through it.

Current Loop

A closed loop of wire carrying an electric current, which generates a magnetic field.

Magnetic Force

The force exerted by a magnetic field on a magnet, another moving charge, or a current-carrying wire.

Attraction and Repulsion

Forces that cause magnets to pull together (attraction) or push away (repulsion) based on their poles.

Electron Beam

A stream of electrons that can be deflected by a magnetic field.

North Pole of a Magnet

The end of a magnet that points toward the Earth's geographic north when allowed to pivot freely.
