Question
Consider a coil and a magnet.
Current is induced in the coil when:
I. coil and magnet both are at rest.
II. the coil is at rest and the magnet moves along x.
III. magnet is at rest and coil moves along x.
IV. both coil and magnet move along y with the same speed.
The correct statements are:
- III and IV
- I and IV
- I and II
- II and III
Hint:
The current is induced when the coil or magnet is moved along x-axis.
The correct answer is: II and III
Current is induced in the coil when II. the coil is at rest and the magnet moves along x. and III. magnet is at rest and the coil moves along x.
- The current is induced in a coil as electromagnetic induction takes place.
- The relative motion between the coil and the magnet creates an electromagnetic induction.
- The current is induced when the coil or the magnet moves along the x-axis.
