Question

Isha works as a ship inspector. She often uses a small device that tests the structures of metal

panels. Her gauge (meter) breaks and out of it two bar magnets fall. Isha investigates the polarities of

the two permanent magnets so she can fix the gauge. When the two magnets are placed on a sheet of

paper as shown in Diagram, Isha feels an attraction between the magnets.
(i)Name a metal/alloy that is suitable to produce a permanent magnet.

(ii) What conclusion can she draw about the polarities of A and B?

(iii) Isha places a small plotting compass between the two magnets and draws the field lines on

the sheet of paper. The arrow of the compass always points towards A. What is the polarity of A and

B?

(a) A = ………………………………..… B = …………………………………………​
