I have just learned electromagnetic induction and it states that if you move a magnet through a solenoid, you would get an induced current.
Say, if you have a copper solenoid, and if you want to move a magnet through it, there will be something (maybe, a force) that would prevent the magnet from entering into the solenoid. Similarly, if you want to withdraw the magnet out of the solenoid, that 'something' would try to make the magnet stay in the solenoid.
According to Lenz's law, the mechanical energy to overcome that 'something' would be converted to electrical energy (the induced current).
So, what is that something?
