4. LENZ’S LAW
• There is an induced current in a closed
conducting loop if and only if the magnetic
flux through the loop is changing. The
direction of the induced current is such that
the induced magnetic field always opposes
the change in the flux

6. Direction of induced current
In both cases, magnet
moves against a
force.
Work is done during the
motion & it is transferred as
electrical energy.

7. FLEMING’S RULES
• Physics two rules used as mnemonics for the
relationship between the direction of current
flow,motion and magnetic field in electromagnetic
induction. The hand is held with the thumb first,
and second fingers at a right angle, respectively
indicating the direction of motion, field and electric
current. The left hand used for electric motor and
right hand for dynamos.

8. Fleming Left Hand Rule

9. Fleming Right Hand Rule
