QJEEM21Ph2949: JEE Main 2021 Physics - Class 12 JEEM21Ph2949 Solution: A coil is placed in a magnetic field as shown below : A current …

A coil is placed in a magnetic field B→\overrightarrow B as shown below :

JEE Main 2021 (Online) 31st August Evening Shift Physics - Electromagnetic Induction Question 63 English

A current is induced in the coil because B→\overrightarrow B is :

Multiple Choice Options

  • A Outward and decreasing with time
  • B Parallel to the plane of coil and decreasing with time
  • C Outward and increasing with time
  • D Parallel to the plane of coil and increasing with time

Step-by-Step Verified Solution

B→\overrightarrow B must not be parallel to the plane of coil for non zero flux and according to lenz law if B is outward it should be decreasing for anticlockwise induced current.
