A magnetic field is defined as the path along which the unit north pole tends to more in a magnetic field if free to do so. They diverge from the north pole of a bar magnet and converge in its south pole. Onside the magnet they move from south pole to north pole.
1. Magnetic field lines are closed continuous curves. True or false?
a. TRUE
b. FALSE
2. The magnetic lines of force do not intersect one another. True or false?
a. TRUE
b. FALSE
3. What will be the correct method to find the direction of field lines if they happen to intersect?
a. They are intersecting each other so direction can not be found
b. The direction will be opposite to the intersection
c. Tangents will be drawn to find out direction of field lines
d. Triangles will be drawn to find field lines
4. They diverge from the south pole of a bar magnet and converge its north pole. True or false?
a. TRUE
b. FALSE
5. Like poles of a magnet ______ and unlike poles of a magnet _____.
a. Attract, attract
b. Repel, repel
c. Attract, repel
d. Repel, attract
