A time-varying electric field:

Question

G1 Physics · Accepted Answer

Ampere-Maxwell law is ∮B·dl = μ₀[I + ε₀(dΦₑ/dt)], where I denotes conduction current. Even if I = 0, a changing electric flux can make the second term non-zero. Therefore a time-varying electric field can produce a magnetic field even in a region where conduction current is zero. Correct option: B.
