Parts and what they mean

• Bar magnet (छड़ चुंबक) — Its N-pole faces the coil. Field lines leave the N-pole, so moving it changes the flux through the coil.
• Velocity of the magnet (चुंबक का वेग) — (a) towards the coil → flux increases; (b) away → flux decreases. Faster motion → larger deflection.
• Coil (closed through G) (कुंडली (G से बंद)) — An emf is induced only while the flux through it is changing.
• Induced current (front of the turns) (प्रेरित धारा (फेरों का सामने वाला भाग)) — Arrows show the current on the near side of each turn. It reverses when the motion reverses.
• Induced pole on the near face (निकट वाले फलक पर प्रेरित ध्रुव) — (a) N faces the approaching N → repulsion; (b) S faces the receding N → attraction. Either way the motion is opposed (Lenz’s law).
• Coil seen from the magnet’s side (चुंबक की ओर से देखी गई कुंडली) — (a) counter-clockwise current = N face; (b) clockwise current = S face (as NCERT states).
• Galvanometer (गैल्वेनोमीटर) — Centre-zero meter. The needle deflects one way in (a) and the opposite way in (b); no deflection when the magnet is still.
