Question

Electromagnetic induction: the magnetic force makes makes an emf due to changing the magnetic flux, the force will be Maximum when the magnetic flux is perpendicular to the conductor ? what is meant by perpendicular ? cos0 (by rule of flux) or sin90 ? thank you.

Answer 1

Sin90 because it is perpendicular to the flux

Answer 2

Faraday's Principle of Electromagnetic Induction states that the emf induced in a loop due by a changing magnetic flux is equal to the rate of change of the magnetic flux threading the loop. The magnetic flux threading a coil of wire can be changed by moving a bar magnet in and out of the coil.
