Magnetic Effects Of Current
A magnet is not the only thing that produces magnetic effects. an electric current in a conductor also produces magnetic field. Whenever current is passed through a conductor it behaves as a magnet. Suppose a straight current carrying conductor is hung vertically, and an electric current is flowing from North to south i.e. from up to down. In this situation, the direction of the magnetic field will be clockwise and if the same current is flowing from south to north through the same conductor, the direction of magnetic field will be anti- clockwise. In similar way we can observe the magnetic field produced by different current carrying conductors like loop, solenoid etc.
The phenomenon that when electric current passes through a wire, then the current carrying wire behaves like a magnet is known as a magnetic effect of current. It was discovered by a scientist Hans Christian Oersted who found that when electric current is passed in a wire, then the compass needle placed near it got deflected from its usual North - South position.

10thAbout Abhyas metholodology the teachers are very nice and hardworking toward students.The Centre Head Mrs Anu Sethi is also a brilliant teacher.Abhyas has taught me how to overcome problems and has always taken my doubts and suppoeted me.
Shreya Shrivastava
8thOne of the best institutes to develope a child interest in studies.Provides SST and English knowledge also unlike other institutes. Teachers are co operative and friendly online tests andPPT develope practical knowledge also.
Aman Kumar Shrivastava
10thA marvelous experience with Abhyas. I am glad to share that my ward has achieved more than enough at the Ambala ABHYAS centre. Years have passed on and more and more he has gained. May the centre flourish and develop day by day by the grace of God.

7thMy experience with Abhyas academy is very good. I did not think that my every subject coming here will be so strong. The main thing is that the online tests had made me learn here more things.
Hiya Gupta
8thAbhyas Methodology is very good. It is based on according to student and each child manages accordingly to its properly. Methodology has improved the abilities of students to shine them in future.
Manish Kumar
10thIt has a great methodology. Students here can get analysis to their test quickly.We can learn easily through PPTs and the testing methods are good. We know that where we have to practice
