The electrical resistance of a conductor is a measure of its opposition to the flow of the electric current.

When the magnetic flux which travels through a coil varies, an electric current is generated in the latter which can light up a bulb.

Concept of density

To calculate what the magnetic field near a conductor is like, you can use Ampère's Law. The visual will help you to understand it.
