WebThen be sure to explain that the way to use the compass is to turn it until the “N” is where the needle is pointing. Yes, that is North, but now the compass will also show you … WebQ. A student performs an experiment to study the magnetic effect of current around a current carrying straight conductor. He reports that: (i) the direction of deflection of the north pole of a compass needle kept at a given point near the conductor remains unaffected even when the terminals of the battery sending current in the wire are interchanged. WebThe compass box is rotated till the 90-90 line becomes parallel to the plane of the coil. Then the apparatus as a whole is rotated till the aluminium pointer reads 0-0. Close the circuit. Adjust the rheostat until the deflection lies between 30 and 60 degrees. Note down the deflection of the compass needle and the current. mihawk current bounty
