A rigid circular loop of radius `r` and mass `m` lies in the `XY-` plane of a flat table and has a current `I` flowing in it. At this particular place. The Earth's magnetic field `vec(B)=B_(x)i+B_(z)k`. The value of `I` so that the loop starts tilting is `:`

A rigid circular loop of radius r & mass m lies in the xy plane on a flat table and has a current I flowing in it At this particular place the earth's magnetic filed is B =B_(x) hati +B_(y) hatj How large must I be before one edge of the loop will lift from table Repeat if , oversetrarr(B) = oversetrarr(B_(x)) hati + oversetrarr(B_(z)) hatk .
