6. Two circular coil turns are so arranged in two mutually perpendicular planes that the centres of the turns coincide. The radius of each coil is 2 sm and the currents flowing through the turns I1= I2 =5 A. Find the intensity of the magnetic field at the centre of these turns.
Answer
Current in coil I1=I2=5A
Radius of each coil R=2cm
Magnetic field due to first coil
Due to second coil
Therefore magnitude of magnetic field at centre
Putting all values
B=0.02T
