Answer 2

To solve this problem, we can use the formula for the force on a current-carrying conductor in a magnetic field:

F = BILsinθ

where: - F is the force on the conductor, - B is the magnetic field strength (induction), - I is the current in the conductor, - L is the length of the conductor, - θ is the angle between the conductor and the magnetic field.

Given: - Magnetic field strength (induction) B = 5 * 10^(-2) Tl - Length of the conductor L = 0.8 m - Current in the conductor I = 15 A - Angle between the conductor and the magnetic field θ = 30 degrees - Displacement of the conductor s = 1.8 m

Calculating the Force on the Conductor:

Using the formula F = BILsinθ, we can calculate the force on the conductor.

F = (5 * 10^(-2) Tl) * (15 A) * (0.8 m) * sin(30 degrees)

Evaluating the above expression, we find:

F ≈ 0.2 N

Therefore, the force acting on the conductor is approximately 0.2 Newtons.

Calculating the Work Done by the Magnetic Field:

The work done by the magnetic field on the conductor can be calculated using the formula:

W = F * s * cosθ

where: - W is the work done by the magnetic field, - F is the force on the conductor, - s is the displacement of the conductor, - θ is the angle between the force and the displacement.

Given: - Force on the conductor F = 0.2 N - Displacement of the conductor s = 1.8 m - Angle between the force and the displacement θ = 30 degrees

Using the formula, we can calculate the work done:

W = (0.2 N) * (1.8 m) * cos(30 degrees)

Evaluating the above expression, we find:

W ≈ 0.31 J

Therefore, the work done by the magnetic field on the conductor is approximately 0.31 Joules.
