Why Do Speakers Have Magnets?

Why Do Speakers Have Magnets? Speakers have magnets because magnets create an opposing magnetic field which results in vibrations which are the sounds we hear. Let’s explain a bit further. As you already know, for speakers to work, they need electric current. This current goes through a coil in the speaker and creates a magnetic [...]
