Answer 1

the answer is (3)

explanation:

as according to the Fleming's left hand rule the center finger directs the direction of the current and as we know that the direction of the current is always opposite to the direction of electron, the direction of the current will be towards the north. Then point the index finger to the direction of the magnetic field. So if we look at the thumb, it will be pointing inside the page.

So, your answer for this question is (3)
