He does a great job of explaining Faraday’s Law of Induction and how a fluid can be the conductor that moves through a magnetic field and has a measurable current induced in it. The current ...

Move the magnet quickly towards the coil and stop. Move the magnet quickly away from the magnet. Flip the magnet pole and repeat steps 1-2. For maximum flux change, hold the magnet close to the coil ...

The fields can cause forces with other nearby magnets which can be used to make motors spin and loudspeakers produce sound. Electromagnetic induction - Higher - AQA Electromagnetic induction can ...
