Give reason when electricity passes through a wire, it deflects the compass needle.
Thus, the magnetic field produced by the current carrying wire is the reason to deflect.
What will happen to a compass needle when the compass is placed below a wire with needle parallel to it and a current is made to flow through the wire ? Give a reason to justify your answer.
Question 6 When the current is switched on through a wire, a compass needle kept nearby gets deflected from its north-south position. Explain.
WHAT CAUSES DEFLECTION OF THE COMPASS NEEDLE WHEN CURRENT FLOWS THROUGH A WIRE NEARBY ?
