Question

1-A compass is held horizontally. The silver end of the needle points towards geographic south and the blue end points towards geographic north. The compass is then brought near one pole of a horseshoe magnet. The blue end of the compass points towards this pole. What is the polarity of this pole on the magnet?

2-Two bar magnets are arranged so that the ends face each other in a line as shown below. At the spot “x”, the north pole of a compass needle points to the right (east). In what direction will the compass needle point when it is placed at position ‘y?’

Answer 1

1) magnetic north pole will be towards geographical south pole, therefore blue end is south pole. The opposite poles of magnets attract each other, therefore horse shoe is north pole

2) magnetic fields at X and y are in opposite directions, therefore at y, direction of needle will be towards west.
