LoginA magnet is moving towards a coil along its axis and the emf induced in the coil is epsilon. If the coil also starts moving towards the magnet with the same speed, the induced emf will be ____
Class 12 Physics in Class 12 3 years ago
`epsilon/2`
`epsilon`
`2epsilon`
`4epsilon`
`THEREFORE emf_1 prop v` where v is relative velocity [ `because` B and l are constant]
Here when relative velocity becomes 2V, the induced `emf_2 prop 2v`,
`therefore (emf_2)/(emf_1)=(2v)/v`
`therefore emf_2=2xxemf_1`
`therefore emf_2=2 epsilon "" [ because emf_1=epsilon]`
