Q7. A conductor of length 1 m moves with a velocity of 50 m s⁻¹ at an angle of 30° to the direction of a uniform magnetic field of flux density 1.5 Wb m⁻². What is the e.m.f induced in the conductor?
A37.5 V
B50.5 V
C75.0 V
D80.5 V
Correct Answer: A
iven information:
Length of conductor, l = 1 m
Velocity, v = 50 m s⁻¹
Angle between velocity and magnetic field, θ = 30°
Magnetic flux density, B = 1.5 Wb m⁻²
Solution:
Step 1: Formula for motional e.m.f
The induced e.m.f in a conductor moving in a magnetic field is given by:
ε = B l v sin θ
Step 2: Substitute the values
ε = 1.5 × 1 × 50 × sin 30°
Step 3: Calculate sin 30°
sin 30° = 0.5
Step 4: Complete the calculation
ε = 1.5 × 50 × 0.5 = 1.5 × 25 = 37.5 V
