A semicircular wire of radius 5.0 cm carries a current of 5.0 A. A magnetic field B of magnitude 0.50 T exists along the perpendicular to the plane of the wire. Find the magnitude of the magnetic force acting on the wire.

Explanation

To find the magnitude of the magnetic force acting on a semicircular wire carrying a current in a magnetic field, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Given Values:**
- Radius of the semicircular wire, \( R = 5.0 \, \text{cm} = 0.05 \, \text{m} \)
- Current flowing through the wire, \( I = 5.0 \, \text{A} \)
- Magnetic field strength, \( B = 0.50 \, \text{T} \)
