Q. Fill in the blanks in the following passage(s) from the words given inside the box.

magnet, carrying magnetic effect, electricity, the magnitude of current deflection increases, eastwards, southwards.
Oersted was the first to put forth the direct relation between _______ and magnetism. He conducted several experiments to determine the _______ of a current _______ wire. The following describes the Oersted experiment conducted to establish that a current carrying wire acts as a _______.
A long straight wire is connected to an external battery and an electric current is passed through it. When a magnetic needle is placed below the wire such that the wire is parallel to the axis of the magnetic needle and the current flows in the south to north direction, a deflection in the needle is observed. It is observed that the north pole of the needle is deflected westwards and as the _______ is increased, the deflection, _______ till the north pole of the needle turns towards exact west. It is also observed that if instead of placing the magnetic needle below the wire, if it was placed above the wire, the north pole of the magnetic needle is deflected _______ .

When we bring a magnetic needle near a current carrying conductor it gets deflected. This deflection is an example of:
