Does the magnet affect the ballast?
If your magnet is just outside the ballast, it won't make any difference.
Don't. If it's close to the electronic ballast, the inductance is the circuit core, and it won't make any difference. If your magnet is just outside the ballast, it won't make any difference.
If you're talking about electronic ballast. Will, when the magnet close to the magnetic ring transformer, magnetic field will change the magnetization curve of the transformer core to form ring circular and saturated point, this will change the work frequency of the electronic ballast, serious when the ballast to stop working.
