A coil is placed in magnetic field such that plane of coil is perpendicular to the direction of magnetic field. The magnetic flux through a coil can be changed:
A. By changing the magnitude of magnetic field within the coil.
B. By changing the area of coil within the magnetic field.
C. By changing the angle between the direction of magnetic field and the plane of the coil.
D. By reversing the magnetic field direction abruptly without changing its magnitude.
Choose the most appropriate answer from the options given below:
(1) A and B only
(2) A, B and D only
(3) A and C only
(4) A, B and C only
- (1) A and B only
- (2) A, B and D only
- (3) A and C only
- (4) A, B and C only
Correct answer: (4) A, B and C only
Solution
The correct option includes all factors that can change the magnetic flux through the coil: altering the magnetic field strength (A), changing the area of the coil (B), and adjusting the angle between the magnetic field and the coil's plane (C). Each of these factors directly influences the amount of magnetic flux passing through the coil.
