How do you tell alternator is bad?
The best way is to drive it to your nearest auto parts store and have it tested. You can test it somewhat yourself. Start the engine and use a volt meter to test the voltage that is being supplied by the alternator for the battery. If it is less than 13.5 volts the alternator is bad.
Will the magnetic pull disappear when alternator is bad?
The way to test an alternator is to take it out and take it to a parts store, most will test it for free. If you want to test your alternator yourself you will need a volt meter. Start the car and have someone rev the motor to 2000 rpms and put your volt meter across the battery terminals ( pos to pos, neg to neg ). You should read 13.5 to 14 volts. If the reading is higher the voltage regulator is bad. If the reading is lower your alternator is not charging the battery sufficiently.

How much volt battery can be charged by an alternator?
If we are talking about cars only: the system that charges the 500 volt battery in a Hybrid is a Alternator. So in theory there is no limit. Most cars are "12 volt" (common usage, incorrect) systems.
