AP EAMCET2015PhysicsMagnetic Effects of Current
Two long straight parallel conductors 10 ~cm apart, carry equal currents of magnitude 3 ~A in the same direction. Then, the magnetic induction at a point midway between them is
Options
- A2 10⁻⁵ ~T
- B3 10⁻⁵ ~T
- Czero
- D4 10⁻⁵ ~T
Correct answer
C. zero
Step-by-step solution
At the mid point of two conductors, the magnetic induction. B₁=B₂=B and B ₁ is anti |^ r to B ₂ . Therefore, the net magnetic induction due to two wire at the mid points is B_ N =B₁-B₂=0
