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` .

`(mg)/(pisqrt(B_x^2+B_2^2))`

`(mg)/(pirB_x)`

`(mg)/(pirB_z)`

`(mg)/(pisqrt(B_xB_z))`
