Calculation of the Force on a Current in a Straight Conductor

To calculate the force on a current in a straight conductor, we can use the formula:

F = BIL sin(θ)

Where: - F is the force on the conductor (in Newtons) - B is the magnetic field induction (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 magnetic field (in degrees)

In this case, we have the following values: - Length of the conductor (L) = 1 m - Current flowing through the conductor (I) = 2 A - Magnetic field induction (B) = 5 mT (or 0.005 T) - Angle between the current and the magnetic field (θ) = 45 degrees

Let's substitute these values into the formula and calculate the force:

F = (0.005 T) * (2 A) * sin(45°)

To calculate the sine of 45 degrees, we can use the trigonometric function sin(45°) = 0.7071.

F = (0.005 T) * (2 A) * 0.7071

Simplifying the equation:

F ≈ 0.0071 N

Therefore, the force on the current in the straight conductor is approximately 0.0071 Newtons.

Please note that the above calculation assumes that the conductor is in a uniform magnetic field and that the current is flowing perpendicular to the magnetic field. If the angle between the current and the magnetic field is different, the force will be different as well.

I hope this helps! Let me know if you have any further questions.
