I have some things that need to be Magnectically Shielded. What makes something magnectically shielded? And can I make it at home? let me know, thanks,
You could try some bucking magnets. You stick them on the back of your driver to cancel out magnetic fields.
The only drawbacks are, they're difficult to apply because the magnets tend to want to move away from one another... and also, once adhered, the bucking magnet(s) will alter the driver's T/S parameters slightly.
