Question

A bar magnet is placed north-south with its north pole due north. The points of zero magnetic field will be in which direction from centre of magnet

• A. north and south
• B. east and west
• C. north-east and south-west
• D. north-east and south-east

Answer 1

The correct option is B east and west

At the points North to the bar the field will be in same direction as of earth's magnetic field similarly in south also.
But on the east and west of the centere of the bar magnet the field will be opposite to the earth's magnetic field therefore, The possibilty of lying of zero magnetic field points is on east and west sides of the center of the bar magnet.
