Problem

A straight segment of wire 0.25 m long carries a current of 3.0 A. The wire is placed in a region where a uniform 0.40 T magnetic field exists, making an angle of 30∘30^{\circ} with the direction of the current. What is the magnitude of the magnetic force on the wire? (a) 0.26 N0.26\,\text{N} (b) 0.15 N0.15\,\text{N} (c) 0.30 N0.30\,\text{N} (d) 0.075 N0.075\,\text{N}
