Answer:
Resultant magnetic field =
Explanation:
We are given that two long straight, parallel wires separated by a distance 20 cm
Le two wires A and B
Current flowing in wire= =30 A
Current flowing in wire B=40 A
We have to find the magnitude of magnetic field at a point 15 cm from wire A and 25 cm from wire B
Magnetic field due to current
Magnetic field due to current T
Magnetic field due to current T
Magnetic field due to current
Angle between
Resultant magnetic field =
Resultant magnetic field =
Resultant magnetic field =
Resultant magnetic field =
Resultant magnetic field =
