Electricity vs. Magnetism: Know the Difference
By Shumaila Saeed || Updated on December 25, 2023
Electricity is the movement of electrons creating an electric charge, whereas magnetism is the force exerted by magnets when they attract or repel each other.
Key Differences
Electricity involves the flow of electrons, creating an electric current used in power systems, while magnetism is a property of materials that respond to an applied magnetic field, often utilized in compasses and hard drives.

Electricity
A property of certain of the fundamental particles of which matter is composed, called also electric charge, and being of two types, designated positive and negative; the property of electric charge on a particle or physical body creates a force field which affects other particles or bodies possessing electric charge; positive charges create a repulsive force between them, and negative charges also create a repulsive force. A positively charged body and a negatively charged body will create an attractive force between them. The unit of electrical charge is the coulomb, and the intensity of the force field at any point is measured in volts.

Magnetism
The property, quality, or state, of being magnetic; the manifestation of the force in nature which is seen in a magnet. At one time it was believed to be separate from the electrical force, but it is now known to be intimately associated with electricity, as part of the phenomenon of electromagnetism.

Electricity
Any of several phenomena associated with the accumulation or movement of electrically charged particles within material bodies, classified as static electricity and electric current. Static electricity is often observed in everyday life, when it causes certain materials to cling together; when sufficient static charge is accumulated, an electric current may pass through the air between two charged bodies, and is observed as a visible spark; when the spark passes from a human body to another object it may be felt as a mild to strong painful sensation. Electricity in the form of electric current is put to many practical uses in electrical and electronic devices. Lightning is also known to be a form of electric current passing between clouds and the ground, or between two clouds. Electric currents may produce heat, light, concussion, and often chemical changes when passed between objects or through any imperfectly conducting substance or space. Accumulation of electrical charge or generation of a voltage differnce between two parts of a complex object may be caused by any of a variety of disturbances of molecular equilibrium, whether from a chemical, physical, or mechanical, cause. Electric current in metals and most other solid coductors is carried by the movement of electrons from one part of the metal to another. In ionic solutions and in semiconductors, other types of movement of charged particles may be responsible for the observed electrical current.
