Electromagnetism Lecture Notes

A set of vocabulary flashcards covering key concepts in electromagnetism, including definitions and descriptions of terms.

Electromagnetism

A branch of physics involving the study of electric fields, magnetic fields, and their interactions.

Electromagnetic induction

The process of inducing a current in a loop when the magnetic field through the loop is changing.

Magnetic field

A space where ferromagnetic materials experience a force of attraction or repulsion; it is a vector quantity.

Ferromagnetic materials

Materials that are easily magnetized, such as iron, cobalt, and nickel.

Field lines

Imaginary lines that represent the direction and strength of a magnetic field, always flowing from north to south.

Noncontact force

A force that does not require physical contact to act on an object, such as magnetic, electrostatic, and gravitational forces.

Magnetic force

The force exerted by a magnetic field, it can attract or repel other magnets or magnetic materials.

Electrostatic force

The force between charged particles, which can also be attractive or repulsive.

Gravitational force

The attractive force that acts between any two masses.

Poles of a magnet

A magnet always has two poles: north and south.
