Question

Which of the following expressions describes better the generalized Ampere's law? a, b, c, or d.

Which of the following expressions describes better the generalized Ampere's law? a. The generalized Ampere's law is valid only when a capacitor is present. b. Implicit in the generalized Ampere's law is the fact that magnetic fields can be generated by either currents, or changing electric fields, or both. c. The generalized Ampere's law helps to understand that only currents that change with time are able to generate magnetic fields. d. The generalized Ampere's law is valid only if the conduction current is continuous in space.

Explanation / Answer

Implict in the generalized Amperes law is the fact that magnetic fields can be generated by either currents or changing electric fields or both.

Therefore correct option is (b).
