A current of 10 A is flowing from east to west in a long straight wire kept on a horizontal table. The magnetic field developed at a distance 10 cm verticaly above the wire is:
- 1.2 \(\times\) 10-5 T, acting towards south
- 2 \(\times\) 10-5 T, acting towards north
- 3 \(\times\) 10-5 T, acting downwards
- 2 \(\times\) 10-5 T, acting upwards
Answer
(B) 2 10 -5 T, acting towards north
