A current loop consists of two identical semicircular parts each of radius R, one lying in the x-y plane and the other in x-z plane. If the current in the loop is i, the resultant magnetic field due to two semicircular parts at their common centre is

`(mu_(0)i)/(sqrt2R)`

`(mu_(0)i)/(2sqrt2R)`

`(mu_(0)i)/(2R)`

`(mu_(0)i)/(4R)`
