Question

In some textbooks the magnetic field lines are called magnetic lines offorce this nomenclature is avoided since it can be confusing. Unlike electrostatics the field lines in magnetism do not indicate the direction of the force on a (moving) charge,

Answer 1

The force around the electrical charge particle is called an electrical field or electric field intensity. In other words, it is an area around the electric field where the force line exists. It has magnitude and direction. Hence it is a vector quantity.The symbol E expresses the electric field, and it is measured in newton/coulomb.

The region around the electric charge where the electric force exists is called an electric field. The area around the magnet where the pole of the magnet exhibits a force of attraction or repulsion is called a magnetic field.

The SI unit of an electric field is the Newton/coulomb, whereas the SI unit of magnetic field is Tesla.
