Solution

A current carrying conductor produces a magnetic field around it and the magnetic needle in this magnetic field experience a force due to which it deflects to align itself in the direction of the magnetic field.

What happens to the needle of a compass if you place the compass near a current carrying wire?

What happens to the needle of a compass kept nearby when electric current is switched on in a wire? Why does this happen?

A wire seems to have charges flowing through it. When a compass is kept next to it, the needle deflects. The reason for the deflection is:

Q. Which of the following observations are true for Hans Oersteds experiment?
a. When current passes through the wire the compass needle comes to rest in a direction along the Earths magnetic field.
b. When placed just above the wire, North Pole of the compass needle deflects towards the east when current is passes from A to B.
c. When placed just below the wire, North Pole of the compass needle deflects towards the east when current is passes from B to A i.e. on reversing the direction of current
