CBSE BoardEnglish MediumSTD 12 ScienceJEE physicsAlternating Current1 Mark
Question
Assertion : An alternating current does not show any magnetic effect.
Reason : Alternating current varies with time.
✓

Answer

(b) Like direct current, an alternating current also produces magnetic field. But the magnitude and direction of the field goes on changing continuously with time.
