S-15-SC2-02-oA coil of insulated wire is connected to a galvanometer. Explain what happens if a barif a bar 3magnet with its north pole towards one face of the coil is(i) moved quickly towards the coil,(i) kept stationary inside the coil, and(iii)moved quickly away from the coil ?oil f n turns is n times as large as produced 3 |

Answer» Ans: (i) when magnet is pushed near a bar magnet then it induces current due to electromagnetic induction.(ii) When the bar magnet is withdrawn from inside the coil of the insulated copper wire again the current is induced in the coil but this time it is in reverse direction.(iii) When a bar magnet is held stationary inside the coil then no current is induced that’s why galvanometer will show no deflection. please like the solution 👍 ✔️👍 move quickly toward the coil |
