Question

According to Maxwell’s hypothesis, a changing electric field gives rise to

• A. magnetic field
• B. electric current
• C. an e.m.f.
• D. pressure radiant

Answer 1

Answer: (A)

$\nabla \times B={\mu }_0\left(J+{ϵ}_0\frac{dE}{dt}\right)$
using this equation of maxwell we can say changing electric field $\frac{dE}{dt}$ induces magnetic field.
