Heinrich Friedrich Emil Lenz was a Russian scientist who discover Lenz' law. Lenz law is based on the principle of the conservation of energy.
This dude say 'an electric current created by a changing magnetic field will create it's own magnetic field opposing the magnetic field that create it' Confusing right!!!! Well me too when i first start to understand this lenz law,bu it's pretty easy to get it with simple demonstration.
Electricity and electromagnetism are so related to each other. We know that when a electric current flows through a conductor it produce a electric field. If a electric current flows through a coil it produce a magnetic field too. Magnetic field has North pole and South pole same as permanent magnet.
When the N pole of the permanent magnet move towards the end of the solenoid,the end of the solenoid will become a magnetic N pole to oppose the motion of the flat magnet.
When the N pole is pulled away from the end of the solenoid, the end of the solenoid will become a magnetic south pole so as to oppose the motion of the permanent magnet.
