Question

i will mark you as brainlist.. in the 2nd digram and 5th digram in both the wooden cylinder north and south pole is same... can you see..
dono Mai north and south pole same hai ek hi Jaise.. MATLAB ek Mai cylinder ke satth magnet north-north attached hai and ek Mai south-south..
toh fhir galvanometer ki Jo reading hai voh 2nd Valle Mai right Mai rotate Kar rahi hai aur 5th valle Mai left Mai Aisa kyu?
dono koh toh same direction Mai rotate Karna Chahiye fhir kyu?
it is Faraday electromagnetic induction chapter please tell..
bahut mehnat lagti hai Yaar likhne Mai please bata do!​

Answer 1

Answer:

i think it is beacuse of lenz's law .

the current produced is opposing the cause of its production.

see , jab 2nd diagram me magnet ko close laate hai coil ke tb usme jo magnetism produce hota hai wo is tarah se hota hai ki N k samne N aaye jisse ki wo magnet ko repel kr sake. isse jo current flow hogi uski direction decide hogi by right hand thumb rule .

similarly in 5th case jab magnet ko coil k pas laya jata hai , tb coil magnet ko repel krne k lie end m S pole bna deti hai , aur current flow hota hai by right hand thumb rule.

isilie the direction of. current in both of the coils is different..

as the coil has to impose different poles at the end , in both the cases , the direction of current is different.
