What happens to the steel cylinder on the circuit breaker if a large current flows through the coil?

I take it you mean the iron (rather than steel) core of the solenoid. If the current reaches the limit set, it is attracted against a spring by the resulting magnetic field created by the coil around it. The movement trips the switch that cuts the current, and usually stays mechanically latched off until re-set by a local or remote control.
(Some circuit-breakers, called auto-reclosers, re-set themselves once the overload has passed. These are typically used on grid transmission-lines.)

What happens if a circuit has no resistance?
Then the voltage in will equal the voltage out. The purpose of a resistor is to reduce the amount of electrical flow of current. You 'short out' the supply and blow a fuse/circuit breaker.
What usually happens at consumer end when the current carrying capacity of transformer is exceeded?
What should happen is that the circuit-breaker should trip to cut off the current before the transformer becomes damaged by overheating.
What are the disadvantage of a circuit breaker or a fuse in a circuit?
The only ones that could affect that decision to put one in is if you're planning on smoking or blowing-up that item in the circuit, or the hassle of changing a 20 cent - 5 dollar item instead of the more expensive item.
What happens to current in a series circuit?
the current in series will be same..
What is voltage error circuit and current error circuit?
A voltage error circuit is called an error amplifier and happens when there are discrepancies between the voltage output and the reference voltage. A current error circuit happens when there is a disruption of flow in an ammeter.
What happens to a switch that automatically opens the current if it is too high?
Circuit Breaker.
Why does an electrical breaker trip when you use a lot of appliances in the house?
since circuit breaker consists of coils they get heated up when high current flows, when this happens the coil get energised and pull the moving contacts to open thus the circuit breaker opens when high current flows.
What happens if you use an ac circuit breaker instead of dc breaker?
A circuit breaker is easier to design for ac than dc because alternating current (ac) naturally goes to zero 100 or 120 times per second and this helps to extinguish any arc. Therefore an ac circuit breaker would not be suitable for dc assuming the same voltage and current ratings.

What is the solution to reducing a circuit breaker from tripping in 1956 home?
The circuit breaker trips when the circuit it is protecting is overloaded. That happens when the wire is at its limit for carrying current. The solution might be to instal an additional power circuit in the house and to make sure the supply from the street is adequate. In both cases an electrician can advise.
What happens if you overload plug sockets?
the circuit breaker will trip or fuse will blow to open the circuit.
What happens when a short circuit occurs in the oven?
Usually the breaker will trip.
What happens to the current measured as more bulbs added?
It is unclear what type of circuit you are referring to, so I'll give both answers.parallel, current increases until too many bulbs have been added, then circuit breaker pops and current drops to zero.series, current decreases and all bulbs dim.

What should happen is that the circuit-breaker should trip to cut off the current before the transformer becomes damaged by overheating.

When a circuit is opened what happens?
Nothing. An open circuit means no current is flowing. When the circuit is closed, current flows, the filament of the bulb is heated by the current and glows, giving off light. But when the circuit is open, nothing happens.
Can circuit breakers help to prevent building fires?
Breakers limit the current on the conductor to a safe level, too many appliances plugged in. You trip a breaker, hopefully you then transfer load to another circuit. Breakers use two different methods to accomplish this, one uses a bimetallic strip and the current passes directly through, too high a current causes the strip to deflect. It acts on a mechanism much like the sear in a guns trigger, the deflection pulls the trigger causing a spring to open the contacts and turn off the circuit. Another type is thermal magnetic, current passing through the breaker causes a magnetic field to act on a coil tripping the breaker. When breakers are wired and work properly they prevent fires!Bending metal opens a switch
