In the following question, sentences of a paragraph have been jumbled and labelled as A, B, C and D. You are required to rearrange the jumbled sentences of the paragraph and mark your response accordingly by selecting the correct option. A: The magnetic field disappears when the current is turned off. B: A current through the wire creates a magnetic field which is concentrated in the hole, denoting the center of the coil. C: An electromagnet is a type of magnet in which the magnetic field is produced by an electric current. D: Electromagnets usually consist of wire wound into a coil. Correct Answer CDBA The correct answer is option 1) i.e. CDBA C is the first sentence because it introduces the subject of electromagnets. D further explains the constituents of an electromagnet. So, D should follow C. D mentions 'wire' and B further tells that a current through the wire creates a magnetic field. So, B should follow D. B mentions the magnetic field with the article 'a' before it. We use a / an before singular countable nouns when we mention them for the first time and hence, the 'magnetic field' mentioned in A refers to the one mentioned in B. So, A should follow B.
