Question

A conducting wire is dropped along east-west direction, then(a) No emf is induced(b) No induced current flows(c) Induced current flows from west to east(d) Induced current flows from east to west

Answer 1

correct Answer is : C

Induced current flows from west to east .

Explanation :

Yes there will be an induced emf induced in the rod.

The reason is due to changing magnitude of earth's magnetic field.

The direction of the induced  current is given by using the Fleming left hand rule  .it's from west to east  

[Fleming left hand rule - hold the thumb,index finger,middle finger in mutually perpendicular direction  :

• thumb shows direction of motion,
• index finger showing direction of magnetic field,
• and middle finger showing direction of emf induced  ]

Answer 2

Answer:

c, induced current flows from wes to east
