7. 7. The direction of the ................. with respect to the current can be found by the Ampere right hand rule or Maxwell's cork screw rule

• electric field

• 7. magnetic field

• magnetic flux

• electric flux

8 . If a right handed cork screw is rotated in such a way so that it moves in the
direction of flow of current through the conductor, then the direction of    rotation
of screw gives the direction of magnetic lines of force is called .......................

• Flemings left hand rule

• Maxwell's cork screw rule

• Flemings Right hand rule

• len's law

• North Pole
• South Pole
• East Pole
• West Pole

10. 10. If the current is in anti-clock wise direction, then the magnetic field produced is
    normally outwards and the face of the coil be haves as ...............

• North Pole
• South Pole
• East Pole
• West Pole
