Questions
Two identical magnetic dipoles of magnetic moments each, are placed at a separation of 2m with their axis perpendicular to each other. The resultant magnetic field at a point midway between the dipoles is
detailed solution
Correct option is B
With respect to 1st magnet, P lies in end side-on position.∴B1=μ04π2Md3(RHS)With respect to 2nd magnet, P lies in broad side - on position.∴B2=μ04πMd3(Upward)B1=10-7 x 2 x 11=2 x 10-7 T, B2=B12=10-7 TAs B1 and B2 are mutually perpendicular, hence the resultant magnetic field isBR=B12+B22=2 x 10-72+10-72=5 x 10-7 TSimilar Questions
Due to a small magnet, intensity at a distance x in the end on position is 9 gauss. What will be the intensity at a distance on broad side on position?
