Which of Maxwell's equations describes the relationship between electric and magnetic fields?

  1. Gauss's law for electric fields

  2. Gauss's law for magnetic fields

  3. Faraday's law of induction

  4. Ampère's circuital law with Maxwell's addition


Correct Option: C
Explanation:

Faraday's law of induction describes the relationship between electric and magnetic fields, stating that a changing magnetic field induces an electric field.

What is the mathematical form of Gauss's law for electric fields?

  1. $\nabla \cdot E = \rho$

  2. $\nabla \cdot B = 0$

  3. $\nabla \times E = -\frac{\partial B}{\partial t}$

  4. $\nabla \times B = \mu_0 (J + \epsilon_0 \frac{\partial E}{\partial t})$


Correct Option: A
Explanation:

Gauss's law for electric fields states that the divergence of the electric field is proportional to the electric charge density.

What is the physical significance of Gauss's law for magnetic fields?

  1. It states that there are no magnetic monopoles.

  2. It relates the magnetic field to the electric current.

  3. It describes the force between two magnetic poles.

  4. It determines the magnetic field inside a material.


Correct Option: A
Explanation:

Gauss's law for magnetic fields states that the divergence of the magnetic field is zero, which implies that there are no isolated magnetic poles.
