Question

A
A bor magnet of geometrical length 18cm has
pole strength
100 Am. Final
the magnetic
dipole dipole
moment
of
the bor magneto
(M = 15 Am​

Answer 1

Answer:

Correct option is

A

15 Am2

Magnetic dipole of a bar magnet

=m×2l

magnetic−length(2l)=65geometric−length

2l=65×18=15cm=0.15m

=m×2l

=100×0.15

=15Am2
