Two very long, straight, and insulated w...

Two very long, straight, and insulated wires are kept at `90^(@)` angle from each other in xy-plane as shown in the figure. These wires carry currents of equal magnitude I, whose directions are shown in the figure. The net magnetic field at point will be:

A

` ( + mu _ 0 I ) /( pi d ) ( hat z ) `

B

Zero

C

` ( mu _ 0 I ) /( 2 pi d ) ( hatx + hat y ) `

D

`- (mu _ 0 I ) /( 2 pi d ) ( hatx + haty ) `

Text Solution

Verified by Experts


` vecB = ( mu _ 0 ) /( 2 pi ) ( I ) / (d) ( hatk ) + ( mu _ 0 ) /( 2pi ) ( I ) /(d) ( - hatk ) `
` vec B = 0 `
