What is different about the voltage when you bring the coil near one pole of the magnet as opposed to the other pole?

Explanation:

This experiment is knows as Faraday's law of induction and as per this a coil is attached to a galvanometer and a magnet is moved near the coil.

As one pole of the magnet is pushed near the coil, the voltage increases and needle in galvanometer deflects. Same phenomena occurs while doing it from different pole , the needle get deflected in different direction.

This shows that the change in magnetic flux induce a electromotive force.

This force is same in quantity for both the poles but of opposite direction.

which piece of furniture will have the most inertia and give the furniture movers the most difficulty in moving?

what experimental evidence led scientists to change from the previous model to this one?

a few of the positive particles aimed at a gold foil seemed to bounce back.

the colors of light emitted from heated atoms had very specific energies.

experiments with water vapor showed that elements combine in specific proportions.

cathode rays were bent in the same way whenever a magnet was brought near them.
