so basically the lenz law says in order not to have change the system, it has to generate or induce a voltage, then creates a current and that current generates magnetic field to cancel out the magnetic field of the original. i got that but..
I would replace ' not to have change the system' by ' not to have energy created out of nothing' and replace 'cancel out' by 'decrease'
