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