A Long straight conductor carrying a current of 2 A is in parallel to another conductor of length 5 cm. and carrying a current 3A. They are separated by a distance of 10 cm. Calculate (a) B due to first conductor at second conductor (b) the force on the short conductor.

Explanation

To solve the problem, we will follow these steps:

### Step 1: Calculate the Magnetic Field (B) due to the first conductor at the location of the second conductor.

The formula for the magnetic field \( B \) at a distance \( D \) from a long straight conductor carrying a current \( I \) is given by:

\[
B = \frac{\mu_0 I}{2 \pi D}
