Difference between Electric Field and Magnetic Field

The magnetic field is the area around a magnetic body or a moving electric charge within which magnetic force acts. It can be generated by moving electric charges. The direction of the magnetic field is indicated by lines. At the same time, the electric fields are produced around the particles, which possess electric charges.

An object with a moving charge always has both magnetic and electric fields. They have some similarities and also have two different fields with the same characteristics. Both fields are inter-related called electromagnetic fields, but they are not dependent on each other.

Difference between Electric Field vs Magnetic Field
Electric Field Magnetic Field
Measured as newton per coulomb, volt per metre. Measured as gauss or tesla.
Proportional to the electric charge. Proportional to the speed of electric charge.
It is perpendicular to the magnetic field. It is perpendicular to the electric field.
An electric field is measured using an electrometer. The magnetic field is measured using the magnetometer.
