Question

Two mutually perpendicular insulated long conducting wires carrying equal currents I, intersect at origin. Then the resultant magnetic induction at point P(2m,3m) will be

  1. 5μ0I2π
  2. 0
  3. μ0I5a
  4. μ0I12π


Solution

The correct option is D μ0I12π

We know that, magnetic field due to an infinite wire is given by,
Bnet=μ0I2π(d)

Due to long wire along x axis, 
magnetic field at P is Bx=μ0I2π(3)  

Due to long wire along y axis, 
magnetic field at P is By=μ0I2π(2)  
 
Net magnetic field at P is Bnet=ByBx
Bnet=μ0I2π(2)μ0I2π(3)
Bnet=μ0I12π
