Q. A coil of wire has 100 turns and is placed in a magnetic field of strength 0.5 T. If the area of the coil is 0.1 m², what is the maximum magnetic flux through the coil? (2022)
A.
5 Wb
B.
0.5 Wb
C.
10 Wb
D.
1 Wb
Solution
Magnetic flux (Φ) = B × A × N = 0.5 T × 0.1 m² × 100 = 5 Wb.
Q. A coil of wire has 100 turns and is placed in a magnetic field of strength 0.5 T. If the area of the coil is 0.1 m² and the magnetic field is perpendicular to the coil, what is the magnetic flux through the coil? (2022)
A.
5 Wb
B.
0.5 Wb
C.
10 Wb
D.
0.05 Wb
Solution
Magnetic flux (Φ) = B × A × cos(θ). Here, B = 0.5 T, A = 0.1 m², and θ = 0° (cos(0) = 1). Thus, Φ = 0.5 T × 0.1 m² × 1 = 0.05 Wb.
Q. A coil with 100 turns has a magnetic flux of 0.02 Wb passing through it. If the flux changes to 0.01 Wb in 2 seconds, what is the induced EMF? (2022)
Q. A current-carrying conductor experiences a force in a magnetic field. What is the direction of this force? (2020)
A.
Parallel to the field
B.
Opposite to the field
C.
Perpendicular to both current and field
D.
In the direction of current
Solution
According to Fleming's left-hand rule, the force on a current-carrying conductor in a magnetic field is perpendicular to both the current and the magnetic field.
Correct Answer:
C
— Perpendicular to both current and field
