A uniform magnetic field of

0.20 \times 10^{-3} \text{ T}

exists in the space. Find the change in the magnetic scalar potential as one moves through 50 cm along the field.

Step-by-Step Verified Solution

**Answer:**

\Delta V = -0.1 \times 10^{-3} \text{ T-m}

. **Step-by-Step Explanation:** Given:

B = 0.20 \times 10^{-3} \text{ T}

,

\Delta r = 50 \text{ cm} = 0.5 \text{ m}

.

\Delta V = -B \cdot \Delta r = -0.20 \times 10^{-3} \times 0.5 = -0.1 \times 10^{-3} \text{ T-m}

[citation:17].
