A circular coil of wire carries a current. PQ is a part of a very long wire carrying a current and passing close to the circular coil. If the directions of currents are those shown in figure, what is the direction of force acting on PQ?
A
Parallel to PQ, towards P
B
Parallel to PQ, towards Q
C
At Right angles to PQ, to right
D
At Right angles to PQ, to the left
Answer
At Right angles to PQ, to the left
Explanation
Solution
Like parallel currents attract and anti parallel currents repel \ PQ moves towards left.
