Two long wires are kept along `x` and `y` axis they carry currents `I&II` respectively in `+ve xx` and `+ve y` direction respectively.Find `vecB` at point `(0,0,d)`

Text Solution

Verified by Experts

The correct Answer is:
`(mu_(0)i)/(2pid)(hati-hatj)`
`vecB=vecB_(1)+vecB_(2)=(mu_(0))/(2pi)l/d(-hatj)+(mu_(0))/(2pi)l/d(-hati)=(mu_(0))/(2pi)l/d(-hati-hatj)`
