Question

Asseration: An emf is induced in a along solenoid by a bar magnet that moves while totally inside it along the solenoid axis. Reason: As the magnet moves inside the solenoid the flux through individual turns of the solenoid changes.

Answer 1

Answer:

Given the solenoid is long, so the net magnetic field lines crossing the solenoid surface do not change on moving the magnet.Hence there is no net change ...

Answer 2

$\Large{\underline{\underline{\bf{Solution:}}}}$

★ Asseration : An emf is induced in a along solenoid by a bar magnet that moves while totally inside it along the solenoid axis.

★ Reason : As the magnet moves inside the solenoid the flux through individual turns of the solenoid changes.

$\rule{150}{2}$

Both Asseration and Reason are correct and Reason is the correct explanation of Asseration.

• Solenoid is not a permanent magnet.
• The force exerted by tge solenoid is equal to the force exerted by tge Permanent magnet.
• Number of rotations increase the power of the solenoid.
• It is an artificial magnet.
