Calculation of Magnetic Field Induction

To determine the magnetic field induction (B) in Tesla, we can use the formula:

B = (F / (I * l * sinθ))

Where: - B is the magnetic field induction in Tesla - F is the force experienced by the conductor in Newtons (12 N in this case) - I is the current in the conductor in Amperes (20 A in this case) - l is the length of the conductor in meters (0.5 m in this case) - θ is the angle between the direction of the magnetic field and the conductor (37° in this case)

Substituting the given values into the formula, we have:

B = (12 N) / (20 A * 0.5 m * sin(37°))

Using the approximation sin(37°) ≈ 0.6, we can simplify the equation:

B ≈ (12 N) / (20 A * 0.5 m * 0.6) ≈ 1 T

Therefore, the magnitude of the magnetic field induction is approximately 1 Tesla.
