Question

the length of a magnet of moment 5Am^2 is 14cm. the magnetic induction at point, equidistant from both the poles is 3.2x 10^-5 wb/m^2 . the distance of the point from each pole is

Answer 1

The distance of the point from either pole is 25 cm.

The magnetic moment of a magnet is a quantity that determines the force that the magnet can exert on electric currents and the torque that a magnetic field will exert on it.

A loop of electric current, a bar magnet, an electron, a molecule, and a planet all have magnetic moments.

Answer 2

Answer:

answer is 25 cm

Explanation:

u×m÷4π×r³=3.2×10^(-5)

u=4π×10^(-7)

r³=10^(-7)×5÷3.2×10^(-5)

r³=0.015625

r=0.25 m

r=0.25 cm

u= mue not
