Three rings, each having equal radius R, are placed mutually perpendicular to each other and each having its centre at the origin of co-ordinate system. If current Iis flowing through each ring then find the magnitude of the magnetic field at the common centre.

Answer»

Solution :B DUE to the ring LYING in XY - PLANE is : `(mu_0I)/(2R)` along Z-axis. B due to the ring lying in YZ - plane is `(mu_0I)/(2R)`along X - axis, and B due to the ring lying in XZ - plane is `(mu_0I)/(2R)` along Y - axis.
`thereforeB_("net") = sqrt(3) (mu_0 I)/(2R)`
