Question

2. What is the effect on the magnetic needle in Oersted's experiment, when (1) a current is passed
through the wire (2) the current through the wire is increased (3) the current through the wire is
stopped (4) the current through the wire is reversed (5) the distance between the magnetic
needle and the wire is increased, keeping the current through the wire constant?​

Answer 1

Explanation:

In Oersted's experiment, when there is no current in the wire, the magnetic needle is at rest along the north-south direction. (1) When a current is passed through the wire, the needle is deflected. (2) When the current through the wire is increased, the deflection of the needle increases.

Answer 2

Answer:

2)when the current through wire is increased the deflection in the needle also increases .

5) when the distance between the magnetic needle and wire is increased keeping the current through the wire in deflection in the needle decreases
