The current in the wire is I. The current comes from infinite parallel to z-axis and finally goes to infinite parallel to y-axis as shown in the figure. Find magnetic field at O in vector form for the following current configurations.
a
μ0.I2πR j^ − 2+7π4 −k^
b
μ0.I4πR j^ + 2+7π4 k^
c
μ0.I4πR j^ + 2+7π4 −k^
d
None of these
detailed solution
Correct option is C
B→=μ0I4πRj^− μ0I4πR3π2 k^ − μ04π I2R π2 k^−μ04π I2R k^ = μ0I4πR j^ − 7π+24k^Talk to our academic expert!
