Answer 3

Calculation of the Force on a Conductor in a Magnetic Field

To calculate the force acting on a conductor in a magnetic field, we can use the formula:

F = BILsinθ

Where: - F is the force on the conductor (in Newtons) - B is the magnetic field strength (in Tesla) - I is the current flowing through the conductor (in Amperes) - L is the length of the conductor (in meters) - θ is the angle between the direction of the current and the direction of the magnetic field (in degrees)

In this case, we have the following values: - Length of the conductor (L) = 20 cm = 0.2 m - Magnetic field strength (B) = 2 T - Current flowing through the conductor (I) = 40 A - Angle between the current and the magnetic field (θ) = 45 degrees

Now, let's substitute these values into the formula and calculate the force:

F = (2 T)(40 A)(0.2 m)sin(45 degrees)

Using a calculator, we can evaluate this expression:

F ≈ 5.66 N

Therefore, the force acting on the conductor in the given conditions is approximately 5.66 Newtons.
