A motor armature conductor of length 0.5 m is exposed to a flux density of 4 Wb / m2.
Calculate the force experienced by the conductor, when the armature current is 5 Amp?
A. 15 N.
B. 20 N.
C. Both A & B.
D. None of these.
Answer: D
Share your understanding of this question with the correct explanation.
To calculate the force experienced by the conductor, we can use the formula:
Force (F) = Length of Conductor (L) x Current (I) x Magnetic Flux Density (B) x Sin(θ)
In this case, the length of the conductor is given as 0.5 m, the current is 5 Amp, and the flux density is 4 Wb/m². However, the angle (θ) between the conductor and the magnetic field is not provided, and it is necessary to know the angle to calculate the force accurately.
Without knowing the angle, we cannot determine the force experienced by the conductor. Therefore, the correct answer is D, None of these.
