Vedclass · Answer

(A) When two wires carrying currents in opposite directions are twisted together,the magnetic field produced by one wire is equal and opposite to the magnetic field produced by the other wire at any point in the surrounding space.As a result,the net magnetic field at any point outside the twisted pair is effectively zero.If the wires are not twisted,they form a loop that generates a magnetic field,which can cause electromagnetic interference $(EMI)$ in nearby sensitive electronic components or circuits.Therefore,twisting the wires minimizes the magnetic flux and prevents unwanted induction in adjacent circuits.Thus,both the Assertion and the Reason are correct,and the Reason is the correct explanation of the Assertion.

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 the wires forms a current loop,and the magnetic field generated by the loop might affect adjacent circuits or components.
