This document discusses electromagnetic laws and rules, including: - Fleming's left hand rule, which describes the direction of force on a conductor in a magnetic field for motor action. - Fleming's right hand rule, which describes the direction of induced current in a conductor moving in a magnetic field for generator action. - Thumb rules and hand rules can be used to determine which law to apply depending on the physical or virtual parameters of the situation.

2. PROCEDURE OF MAKING RULE
OBSERVATION THE MACHINE & GIVE THE PRINCIPLE ON TRIAL-ERROR
METHOD
APPLYING THE INITIALLY DESIGNED PRINCIPLE ON THE MACHINE
COMPARING THE REAL OUTCOME OF THE MACHINE WITH INITIALLY
DESIGNED PRINCIPLE
RULE IS IMPLEMENTED & DECLERED BY THE SCIENTIST & METHOD FOR
PERTICULAR SYSTEM
IF ALL THE CONDITIONS ARE SETISFIED???
YES NO
RULE IS
MODIFIED

9. WHERE & WHEN, WHICH LAW SHOULD BE
CONSIDER???
• FLEMING LEFT HAND RULE – MOTOR ACTION
• FLEMING RIGHT HAND – GENERATOR ACTION
• THUMB RULE – Applicable by considering physical
conditions
• HAND RULE – Applicable by considering virtual
parameters
