Moving Charges And Magnetism

A wire carrying a current \(I\) along the positive \(\mathrm{x}\)-axis has length \(L\). It is kept in a magnetic field \(\overrightarrow{\mathrm{B}}=(2 \hat{\mathrm{i}}+3 \hat{\mathrm{j}}-4 \hat{\mathrm{k}}) \mathrm{T}\). The magnitude of the magnetic force acting on the wire is :
