A current of 5.0 A exists in the circuit shown in the figure. The wire PQ has a length of 50 cm and the magnetic field in which it is immersed has a magnitude of 0.20 T. Find the magnetic force acting on the wire PQ.

Step-by-Step Verified Solution

**Answer:** F=0.5 NF = 0.5 \text{ N}. **Step-by-Step Explanation:** Given: i=5 Ai = 5 \text{ A}, l=0.5 ml = 0.5 \text{ m}, B=0.20 TB = 0.20 \text{ T}. The wire PQ is perpendicular to the magnetic field. F=ilB=5×0.5×0.20=0.5 NF = i l B = 5 \times 0.5 \times 0.20 = 0.5 \text{ N}.
