What are the methods of producing induced emf?
What are the methods of producing induced emf? The induced emf can be produced by changing : (i) the magnetic induction (B), (ii) area enclosed by the coil (A) and. (iii) the orientation of the coil (θ) with respect to the magnetic field. What is the use of induced emf? A motor has coils turning […]
Can you turn off a electromagnet?
Can you turn off a electromagnet? Re: Turning off electromagnet Use a relay. Wire the electromagnet to the relay’s normally closed pins, then run current through the pushbutton switch to the relay coil – when you push the switch, it’ll pull the relay the other way and the electromagnet will shut off.

Can water cycle work without the sun?
Can water cycle work without the sun? Water constantly moves around the Earth and changes between solid, liquid and gas. This all depends on the Sun’s energy. Without the Sun there would be no water cycle, which means no clouds, no rain—no weather!” “And without the Sun’s heat, the world’s oceans would be frozen!” added […]
What are the similarities and differences between fission and fusion?
What are the similarities and differences between fission and fusion? Both fission and fusion are nuclear reactions that produce energy, but the applications are not the same. Fission is the splitting of a heavy, unstable nucleus into two lighter nuclei, and fusion is the process where two light nuclei combine together releasing vast amounts of […]
