Fleming's Left Hand Rule :
 " when a current carrying conductor is placed in a magnetic field , a force is exerted on wire which   Fleming has given .Hold the fore finger, the centre finger and the thumb of your left hand at right angles to one another.
Fore finger points should point to magnetic field direction
Centre finger to current.
then thumb indicates the magnetic force direction "

b]Safety measures commonly used in electric circuits is :
By connecting Fuse in series to house hold circuit
By earthing.

c]Overloading of electric circuits can be avoided by using safety device called as Fuse.
Fuse is made up of tin and copper having lo melting point connected in series.
When more voltage comes through live wire, first fuse wire melts , make the circuit open so that current supply stops. Thus all  electrical appliances are saved from getting damaged.
