A straight current$-$carrying wire is placed horizontally on an east$-$west line in a region of uniform magnetic field. The magnetic field here is due north, parallel to the ground, with a strength of $0\mathrm{.}35$ T$.$ The wire has a mass per unit length of $4\mathrm{.}4$ g$/$cm$.$

How much current is needed to be passed through the wire to keep the wire afloat.$$

Write your answer in the units of A in decimal form with two digits to the right of the decimal point $($e$.$g$.5\mathrm{.}32)$; do not write any units or sign.$$

Correct!
