Problem

A straight conductor of length 0.50 m0.50\,\text{m} carries a current of 5 A5\,\text{A}. Only 0.20 m0.20\,\text{m} of its length lies inside a uniform magnetic field of 0.30 T0.30\,\text{T}, and this portion is perpendicular to the field. What is the magnitude of the magnetic force acting on the conductor while it is in this position? (a) 0.60 N0.60\,\text{N} (b) 0.15 N0.15\,\text{N} (c) 0.30 N0.30\,\text{N} (d) 0.75 N0.75\,\text{N}
