That's a purely arbitrary convention that goes back to the first experiments with electricity (see Ben Franklin).
Anodes are positive in an electrical circuit.
Yes, anodes are positively charged in an electrochemical cell.
Anodes are typically negative in an electrochemical cell.
negative electrode
I doubt this is useful since this was posted 4 years ago, but carbon anodes have to be replaced in commercial use because they react with the oxygen that is reacts with (or so i think), and therefore the co2 that comes from the carbon and metal oxide in the displacement reaction makes the carbon anodes turn into co2 and therefore these anodes need to be replaced

i dont know use rectifier just invert ac to dc and supplied to anodes positive to steel negative
The "anode" is usually considered to be "negative". However in some experiments such as Gel Electrophoresis the anode is positive.
Yes, cathodes and anodes are typically made of metal which is not affected by magnetic fields. Therefore, magnets would not displace cathodes and anodes.
Lithium ion battery anodes offer higher energy density, longer lifespan, and faster charging capabilities compared to other types of battery anodes.
A three phase alternator will have six diodes in the rectifier bridge, three with their anodes connected to the phases, and cathodes commoned to the positive terminal, and three with the cathodes connected to the phases, and anodes commoned to the negative terminal, which is likely the housing of the alternator. The trio diodes arrangement will match the positive rectifiers, i.e. anodes to the phase connections, cathodes (denoted usually by a stripe around the body on small diodes), connected to the D+ terminal
Anodes
Zinc anodes offer a sacrificial method of maintaining the steelwork of the pier.. The anodes 'attract' corrosion thereby extending the life and protecting the steel work. (same as on ships hulls etc)
The anodes and cathodes affect the voltage of the battery all the time. Without them, the battery would not work. The anode provides the positive charge or current. The cathode provides the negative charge or electrons. Part of the anode is down in the battery and part serves as a terminal. Part of the cathode is down in the battery and part serves a a terminal.
