A current I = 5 amp flow through a thin wire as shown in the figure.
(a) Find the magnetic field produced by the current at point O in the figure.
(b) If there exists an external magnetic field `B = (14 hat(i) + 14 hat(j))T`. Calculate the torque acting on the wire.

Text Solution

Verified by Experts

The correct Answer is:
`22.78 mu T` in the direction `hat(k)` (b) `tau = 6.7 (hat(j) - hat(i)) N-m`
