Problem Analysis

We are given a conductor with a mass of 5 * 10^3 kg and a length of 0.25 m. The conductor is placed horizontally in a magnetic field, and a current of 20 A is passed through it. The conductor is in equilibrium. We need to find the magnitude and direction of the magnetic field vector.

Solution

To find the magnitude and direction of the magnetic field vector, we can use the equation:

F = BIL

Where: - F is the force experienced by the conductor, - B is the magnitude of the magnetic field vector, - I is the current passing through the conductor, and - L is the length of the conductor.

Since the conductor is in equilibrium, the force experienced by the conductor must be zero. Therefore, we can set up the equation:

BIL = 0

Simplifying the equation, we get:

B = 0

This means that the magnitude of the magnetic field vector is zero. Therefore, there is no magnetic field present in this scenario.

Conclusion

In the given scenario, the conductor is in equilibrium when a current of 20 A is passed through it in a horizontal position. However, there is no magnetic field present, as the magnitude of the magnetic field vector is zero.
