The bracelet itself will not affect the electronic device, but if you wear a magnetic bracelet with magnetic therapy, it will affect the electronic device.
For people with heart disease, a defibrillator or pacemaker can be implanted in the heart, which can regulate slow heartbeats and irregular heartbeats. If the patient's heart flutters, they go to work. This works through a magnetic field. Wearing a magnetic bracelet may interfere with the proper functioning of the defibrillator and have serious consequences.
A lot of people wear a watch, especially a mechanical watch, with a magnetic bracelet, which may cause the watch to slow or speed up. . But most watches these days are made to ISO764, which means it's non-magnetic and resistant to 6mt magnetic fields, but that doesn't mean they won't be affected. If you are wearing a magnetic bracelet that is very magnetic, it may be affected.
In addition to these, will other electronic products be affected? Magnets shouldn't be a bad thing, at least for most electronics, since most electronics are manufactured to non-magnetic ISO standards these days. As long as you buy the right electronics, you don't have to worry about being affected by them.
