COMEDK · Physics · 21. Magnetic Effects of Current
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
- A open curves
- B closed loops
- C can be open or closed depending on magnetic field
- D no field lines are produced
Answer & Solution
Correct Answer
(A) open curves
Step-by-step Solution
Detailed explanation
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.
