Feb 08, 2021 · Permanent Magnets. When the voice coil receives an electric current and produces a magnetic field, it is repelled by the permanent magnet fixed to the loudspeaker basket. These magnets come in various sizes and materials, but interestingly enough, they aren't magnets at all until the loudspeaker assembly reaches the end of our production line.

Calculate magnetic flux density (formula)

A permanent magnet produces a B field in its core and in its external surroundings. A directional B field strength can be attributed to each point within and outside of the magnet. If you position a small compass needle in the B field of a magnet, it orients itself toward the field direction.

Jan 26, 2021 · Each conductor coiling around its cone becomes an electromagnet when supplied with current. Music is an oscillatory signal. The strength of the electromagnet vacillates as the signal does. However, remember that the electromagnet is placed above a permanent magnet. The two magnets, due to their conflicting polarities, exert a force on each other.
