the magnetic induction field due to a north pole of strength 10Am and 5cm away from the pole in weber/msquare

Question

Samyak Jain · Answer

Magnitude of magnetic induction due to a pole of strength m at a distance r from it is B = ( 0 / 4 )(m / r 2 ) , 0 / 4 = 10 –7 H. m = 10 Am, r = 5 cm = 5 x 10 –2 m So, magnitude of magnetic induction, B = (10 –7 )(10 / 25 x 10 –4 ) = 4 x 10 –12 Wb / m 2 .

Samyak Jain · Answer

There is a slight mistake in calculation. The magnitude of magnetic induction should be B = 4 x 10 –4 Wb / m 2 .
