The law which states that 'a variation in an electric field causes magnetic field', is
- A Faradays law
- B Bio-Savart Law
- C Modified Ampere's Law
- D Lenz's Law
Answer & Solution
Correct Answer
(C) Modified Ampere's Law
Step-by-step Solution
Detailed explanation
Modified ampere circuital law is, ∮B→·dL→=μ0ic+id id is the displacement current that is, id=ε0dϕEdt ⇒∮B→·dL→=μ0ic+ε0dϕEdt Thus, it is clear from the above expression that modified ampere's…
