GCSE Physics

A question gives you the mass of a wire, current, magnetic flux density and length, and asks for the total force acting on the wire. Is this just calculating the magnetic force and adding it to the weight? I'm not sure how you would find the direction of the magnetic force in this case, so I can't tell whether to add or subtract the forces? Any help? This was all the information given.

Total force means consequencial(resultant) force(net force) of some forces which have different directions.

Originally, Electromagnetic force is greater than Gravitational force in nature. So If you know some information about the force direction or generalised coordinates in your problems, just find a resultant force.

But, you didn’t show any information about motion of your problems, I didn’t find exact hint at your problems.
