1. EM Induction with Faraday's and Lenz's Law

So if a wire in a magnetic field moves when a current flows, can you induce a potential difference if you simply move the wire? This is investigated in this video bringing together two laws from both Faraday and Lenz.

 

2. Magnetic Flux and Magnetic Flux Density

A magnetic field is analogous to a field of grass in many ways. The magnetic flux is like the total number of blades of grass, whereas the density is how thickly the grass grows - a stronger field has more grass.
