To find the magnetic moment of the dipole, we need to use the formula:
Magnetic Moment (m) = pole strength (m) x length (l)
Given that the pole strength (m) is 20 Am and the length (l) is 10 cm, we can substitute these values into the formula:
m = 20 Am
l = 10 cm
Converting the length from cm to meters:
l = 10 cm = 0.1 m
Substituting the values into the formula:
m = 20 Am x 0.1 m
Calculating the magnetic moment:
m = 2 Am²
Therefore, the magnetic moment of the dipole is 2 Am², which corresponds to option A.

A magnetic dipole of length 10 cm has pole strength of 20 Am. Find the...
Magnetic dipole moment = Pole strength × Magnetic length.
Magnetic dipole moment = 20 Am × 0.1 m
Magnetic dipole moment = 2 Am2.
Magnetic dipole moment = 20 Am × 0.1 m
Magnetic dipole moment = 2 Am2.
