Magnetic field in a region is changing at a constant rate. As a result, an induced electric field appears in the region which give rise to an emf. Induced electric field lines are

Options

  1. Aopen curves
  2. Bclosed loops
  3. Ccan be open or closed depending on magnetic field
  4. Dno field lines are produced

Correct answer

A. open curves

Step-by-step solution

Induced electric field lines are open loops. It emerges from positive charge and going to infinity and it enters into negative charge coming from infinity.
