Find the force due to a current element of length 2cm and flux density...
Given:
Length of current element (l) = 2 cm = 0.02 m
Flux density (B) = 12 Tesla
Current through the element (I) = 5 A
To Find:
Force due to the current element
Solution:
The force (F) on a current element in a magnetic field is given by the formula:
F = B * I * l * sin(theta)
Where:
B = Flux density
I = Current through the element
l = Length of the current element
theta = Angle between the direction of the current and the magnetic field
In this case, the length of the current element is given as 2 cm, which is equal to 0.02 m. The flux density is given as 12 Tesla and the current through the element is 5 A.
The angle theta is not given in the question, so we assume that the current element is perpendicular to the magnetic field. In this case, the angle between the current and the magnetic field is 90 degrees, and the sine of 90 degrees is 1.
Substituting the given values into the formula:
F = 12 Tesla * 5 A * 0.02 m * 1
F = 1.2 N
Therefore, the force due to the current element is 1.2 Newtons.
Conclusion:
The correct answer is option B, 1.2 N.
Length of current element (l) = 2 cm = 0.02 m
Flux density (B) = 12 Tesla
