Q Force experienced by a magnetic pole when kept in a uniform magnetic field of 4 X 10-5 T - Physics - Magnetism And Matter

Question

Q Force experienced by a magnetic pole when kept in a uniform
magnetic field of 4 X 10-5 T , is the same as the force
experienced by that pole when kept at a distance of 10 cm from an
unknown pole Determine the pole - strength of the unknown pole

Shobhit Mittal · Accepted Answer

the field must be 4*10-5 T because of the magnet at a
distance 10cm
let the magnet be at axial osition B=μ04π
2Md3=4*10-5=10-7*2M0 132M=0 4M=0
2 that the magnetic  momentlet the length of the magnet be lmagnetic strength=0
