Poles Of Magnet|Finding Direction By Magnet|Compass|OMR

Assertion: The magnetic poles of earth do not coincide with the geographic poles. Reason: The discrepancy between orientation of a compass and true north-south direction is known as magnetic declination.

Assertion At the centre of a circular current carrying loop (I_(1)) , there is an infinitely long straight of the circle. Then magnetic force of attraction between two is zero. Reason Magnetic field of I_(1) at centre is inwards, parallel to I_(2) .
