Answer:
Explanation:
vertical magnetic field B_v = 4 x 10⁻⁵ T.
Magnetic field due to horizontal current at point 20 cm above
= (μ₀/4π ) x (2i / R)
= 10⁻⁷ x 2 x 20/ 20 x 10⁻²
= 2 x 10⁻⁵ T
It will act coming out of paper. Hence it will be normal to magnetic field given .
So resultant magnetic field
= √ (4² + 2²) x 10⁻⁵ T
= 4.47 X 10⁻⁵ T .
