ECE :: Electromagnetic Induction
- A laminated iron core has reduced eddy-current losses because
- In case of an inductance, current is proportional to
- An average voltage of 10 V is induced in a 250 turns solenoid as a result of a change in flux which occurs in 0.5 second. The total flux change is
- The law that the induced e.m.f. and current always oppose the cause producing them is due to
- The magnitude of the induced e.m.f. in a conductor depends on the
- A conductor carries 125 amperes of current under 60° to a magnetic field of 1.1 tesla. The force on the conductor will be nearly
- A crack in the magnetic path of an inductor will result in
- Lenz's law is a consequence of the law of conservation of
