magnetic field due to a current in a solenoid digram
Answers
Explanation:
-:Solenoid :-
The solenoid is a long coil containing a large number of close turns of insulated Copper wire.
In this above figure SN whose two ends are connected to a battery B through the solenoid ,it produces a magnetic field around it .
It is found by the experiment that when currect is passed through the solenoid from one end to other end then a magnetic field lines is produces around the current carring solenoid,which is exactly sale as the magnetic field lines around a bar magnet .Which starts from N pole ans enters S. Poles this shows that around any current caring wire a magnetic field is produces but if they are a single straight then the magnetic field strength will be less and if the there if current is pass through a complex group of conductor or a large number of turns ( as seened in a solenoid ) then the magnetic field lines is stronger .
