Textbook brain teaser

If we stop moving a magnet near a coil, what happens to the induced current?

کوائل کے قریب مقناطیس کی حرکت روک دیں تو امالی رو کا کیا ہوتا ہے؟

Solution & explanation

If the coil, magnet and circuit are then stationary and no other flux changes occur, induced emf falls to zero. A resistive circuit’s transient current dies away. The presence of a magnetic field alone is insufficient: changing linked magnetic flux is required.
