Magnetism Lecture Notes

Flashcards about Magnetism

Magnetism

A physical phenomenon produced by the motion of electric charge, resulting in attractive and repulsive forces between objects.

Compass

A navigational instrument that uses a magnetic needle to align with Earth's magnetic field, indicating direction.

Magnetic Field

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

Magnetic Poles

The points on a magnet where the magnetic field is strongest (North and South).

Magnetic Attraction and Repulsion

Similar magnetic poles repel each other, while opposite poles attract each other.

Electric Generator

A device that uses magnets and a coil to convert kinetic energy into electrical energy.

Electric Motor

A device that uses electrical energy and magnets to create motion, often through a coil situated between two magnets that drives an axle.

Natural Magnets

Magnets that are made from naturally magnetic materials.

Electromagnets

Temporary magnets that require electricity to function.

Electric Generator Conversion

Converts kinetic energy to electric energy.

Electrical Motor Conversion

Converts electric energy to kinetic energy.

Electromagnet Usage

Uses electrical energy to generate magnetic force

Magnetism

Force from moving electric charge.
