Concept explainers
To Find: The magnitude and direction of magnetic field at the centre of the square.
Answer to Problem 78GP
Explanation of Solution
Given info:
Side of the square
Current in each wire
Formula used:
Magnetic field due to infinitely long wire:
Where,
Calculation:
Distance of each wire from the centre of the square:
Magnetic Field due to each wire at the centre of the square:
Net magnetic field at the centre of the square:
The direction of net magnetic field is towards left.
Conclusion:
Hence, magnitude and direction of the net magnetic field at the centre of the square:
