Question

what is meant by solenoid ? how does a current carrying solenoid behave ? give its main use .?

Answer 1

A long hallow wire which carries current is called solenoid. In outside the magnetic field is cones from south to north. Inside it is from north to south. Solenoid is current carrying wire.

Answer 2

a coil of many circular turns of insulated copper wire wrapped closely in the shape of a cylinder is called solenoid .


the field lines around a current carrying solenoid is similar to that produced by a bar magnet this means that a current carrying solenoid behaves as a the field lines around a current carrying solenoid is similar to that produced by magnet this means that current carrying solenoid behaves as having north pole and South Pole the strong magnetic field produced inside a solenoid can be used to magnetize a piece of magnetic material like soft iron when placed inside the coil .
