To solve the problem of finding the magnitude and direction of the magnetic field at a point 10 cm from both wires A and B, we will follow these steps: ### Step 1: Understand the Setup We have two long current-carrying wires, A and B, separated by a distance of 20 cm. Wire A carries a current of 10 A, and wire B carries a current of 20 A in opposite directions. We need to find the magnetic field at a point that is 10 cm away from both wires. ### Step 2: Use the Formula for Magnetic Field The magnetic field (B) at a distance (D) from a long straight wire carrying current (I) is given by the formula: \[ ...
