Assertion: In electric circuits, wires carrying currents in opposite directions are often twised together.
Reason: If the wires are not twisted together, the combination of the wires formes a current loop, the magnetic field generated by the loop might affect adjacent circuits of components.

Direction. In the follwing questions, a statement of assertion is followed by a statement of reason. While answering a question, you are required to choose the correct are out of the given four responses and mark it as (A). If both assertion and reason are true and reason is the correct explanation of the assertion, (B) if both assertion and reason are true but reason is not correct explanation of the assertion. (C) if asssertion is true, but reason if false, (D) if both assertion and reason are false Assertion : In electric circuits, wires carrying currents in opposite directions are often twisted together. Reason : If the wires are not twisted together, the combination of wires forms a current loop, the magnetic field generated by the loop, might affect adjecent circuits or components.

(A) : In electric circuits, wires carrying currents in opposite directions are often twisted together. (R) : If the wire are not twisted together, the combination of the wires forms a current loop. The magnetic field generated by the loop might affect adjacent circuits or components.

STATEMENT-1: In electric circuits, wires carrying currents in opposite directions are often twisted together. because STATEMENT-2: The magnetic field in the surrounding space of a twisted wire system is not precisely zero because the wires are not in the same location in space.

Quite often, connecting wires carrying currents in opposite directions are twisted together in using electrical appliances. Explain how it avoids unwanted magnetic fields.
