1)A current-carrying conductor is kept at right angles to the direction of a magnetic field. What happens to the force acting on the wire if the strength of the magnetic field doubles?

the force is doubled.

2)How much current is required to produce a force of 0.96 N on a 75 cm long wire oriented at right angles to a 0.24 T magnetic field?

I=F/BL
0.96/0.24*75
I= 0.050 A
