How can I calculate the magnetic field using electromagnetic induction?

Homework Statement

A .76 meter long wire runs horizontally and carries a current of 28A (left to right). What would be the magnitude and direction of the minimum magnetic field to suspend the wire in mid air if the wire has a mass of 46.6 g/m?

Relevant Equations

I think its F=ILBsin

gotta be honest I am really struggling

Hello mountain, $\qquad$ $\qquad$ !

Unfortunately the PF guidelines require an attempt at solution before we are allowed to assist.

Your relevant equation is good (misses an angle at the end, but for minimum B an angle of $\pi/2$ does the trick).
So what is the problem ? You have I, L and you can calculate F. Then B follows !
