Question

A rigid circular loop of radius r and mass m lies in the x - y plane of a flat table and has a current i flowing in it. At this particular place, the Earth's magnetic field is B → = B x i ^ + B z k ^ . The value of i , so that the loop starts tilting, is, m g π B x 2 + B 2 2, m g π r B x, m g π r B z, m g π r B x B z

M → = i π r 2 k ^ , B → = B x i ^ + B z k ^ To start tilting τ d u e t o m a s s = τ m a g n e t i c m g r = M → × B → m g r = i π r 2 B x i = m g π r B x
