Objective questions of electromagnetic induction-
This assignment contains Objective questions of electromagnetic induction, which will help the students to prepare for class 12th board examination and other competitive exams like JEE/NEET.
- Lenz’s law is a consequence of the law of conservation of:
- (a)charge (b) mass (c) momentum (d) energy
- The law of electromagnetic induction have been used in the construction of a:
- (a)galvanometer (b) voltmeter (c) electric motor (d) generator
- A cylindrical bar magnet is kept along the axis of a circular coil. On rotating the magnet about the axis, the coil will have induced in it:
- (a)a current (b) no current (c) only an em (d) both an emf and a current
- A horizontal straight conductor when placed along south-north direction falls under gravity; there is:
- (a)an induced current from south to north direction
- (b)an induced current from north to south direction
- (c)no induced emf along the length of the conductor
- (d)an induced emf along the length of the conductor
- A car moves on a plane road. Induced emf produced across the axle is maximum when it moves:
- (a)at the poles (b)moves at equator (c) remains stationary
- (d) no emf is induced at all
