Frequently Asked Questions

Q1: What is electromagnetic field?

A1: Branch of physics that deals with electric as well as magnetic phenomena. Both the fields are closely related to each other. A field is a region in which a corresponding value of some physical function exists at each point. There are two types of field. Magnetic field produced by magnetic effect. Electric field produced due to electric changes. Moving charges produce a current. The current carrying conductor produces a magnetic field. Thus, electric and magnetic field are related to each other. This field is called as electromagnetic field.

Q2: What is scalar and vector field?

A2: A physical quantity which is characterized by its magnitude only is called scalar. (Example: speed, mass, temperature, volume, density, electric charge etc). The distribution of a scalar quantity with a definite position in a space is called scalar field. Eg; the temperature of atmosphere where it has a definite value in the atmosphere but there is no need of direction to specify.

A physical quantity which is characterized by its magnitude and as well as direction is called vector. The corresponding field is called vector field, if a quantity which is specified in a region to define a field is a vector. Example, the gravitational force on a mass in a space. This force has a value at various points in a space and also has a specific direction.

Q3: What is electrostatics?

A3: A branch of electromagnetic dealing with the effect of electric charges at rest position.

Q4: Explain coulomb’s law.

A4: The fundamental of electrostatics is coulomb’s law. It was given by Calomel Charles Coulomb, a french army engineer. It says,

‘The force between the two point charges Q1 and Q2 is given by Q1——Q2

  1. acts with the line joining the two point charges
  2. directly proportional to the product of the two point charges Q1 and Q2
  3. It is inversely proportional to the square of the distance between two point charges

Q5: What is electric field intensity?

A5: The force exerted per unit charge is called electric field intensity. It is denoted by E

E= Total Force (N)/Total charge (c).

  • electric field due to point charges
  • electric field due to continuous charges
