Question

what is the difference between the lenz's law and the Fleming right hand rule

Answer 1

Whenever, a current carrying conductor comes under a magnetic field, there will be a force acting on the conductor and on the other hand, if a conductor is forcefully brought under a magnetic field, there will be an induced current in that conductor. In both of the phenomenons, there is a relation between magnetic field, current and force. This relation is directionally determined by Fleming's Left Hand rule and Fleming's Right Hand rule respectively. Directionally means these rules do not show the magnitude but show the direction of any of the three parameters (magnetic field, current, force) if the direction of other two are known. Fleming's Left Hand rule is mainly applicable for electric motor and Fleming's Right Hand rule is mainly applicable for electric generator. In late 19th century, John Ambrose Fleming introduced both these rules and as per his name, the rules are well known as Fleming's left and right hand rule.
