Magnetic field due to currentHard
Question
The magnetic moment of a short magnet is 8 Am2. The magnetic induction at a point 20cm away from its mid point on (i) axial point (ii) equatorial point respectively, will be : -
Options
A.2 × 10-4 and 10-4 T
B.3 × 10-4 and 2 × 10-4 T
C.4 × 10-4 and 3 × 10-4 T
D.None of these
Solution
Baxial point = 2
= 2 × 10-4 T
Beq.point =
= 10-4T
= 2 × 10-4 TBeq.point =
= 10-4TCreate a free account to view solution
