asssertion : when a coil is moved out a magnetic field acting normally to its plane, induced emf is produced. Reason: the induced emf is produced in a coil when it is placed inside the magnetic field |

Answer» Answer: The assertion is correct and reason is wrong. Explanation: Assertion: When a coil is MOVED out a magnetic field acting normally to its plane, induced EMF is produced.Since there is CHANGE in the magnetic field when the coil is moving out, there is a change in magnetic flux induced which in turn has induced an EMF in the coil. dΦ=B⋅dA (change in flux directly proportional to change in area in contact with magnetic field) EMF = dΦ / DT (induced emf is directly proportional to the change in flux density) Whereas the assertion, Given Reason: The induced EMF is produced in a coil when it is placed inside the magnetic field.This is statement is false, as the EMF can't be induced in a stationary coil. Correct reason: The induced emf is produced in a coil due to the change in magnetic flux density when the coil is moved out of the magnetic field.HOPE YOU LIKED MY ANSWER!
