Text Solution

AI Generated Solution

To calculate the magnetic field at a distance of 5 cm from an infinite straight conductor carrying a current of 10 A, we can use the formula for the magnetic field around a long straight conductor: ### Step-by-Step Solution: 1. **Identify the Formula**: The magnetic field \( B \) at a distance \( r \) from a long straight conductor carrying a current \( I \) is given by the formula: \[ B = \frac{\mu_0 I}{2 \pi r} ...
