When an electromagnet is turned on, it generates a magnetic field that attracts the metal reed in the reed switch, causing the switch contacts to close. When the electromagnet is turned off, the magnetic field disappears and the contacts open again. This allows the reed switch to act as a sensor or control device in various applications.

What is switch called that rotates with an electromagnet?
A rotary switch.
What is the function of the switch in the electromagnet crane?
The switch in the electromagnet crane controls the flow of electric current to the electromagnet. It allows the operator to turn the magnet on and off, enabling them to pick up and release loads.
How is electromagnet used in a burglar alarm?
An electromagnet is used in a burglar alarm to create a magnetic contact switch. When the door or window is closed, the electromagnet keeps the switch closed. If the door or window is opened, the magnetic field is disrupted, causing the switch to open and trigger the alarm.
How does an electromagnet switch work?
An electromagnet switch works by energizing a coil of wire to create a magnetic field that attracts a ferrous metal armature to open or close an electrical circuit. When the coil is energized, it creates a magnetic field that pulls the armature towards it, allowing the switch to change its state from open to closed or vice versa. This controlled movement of the armature enables the switch to control the flow of electricity in a circuit.
Does a key or reed switch have a symbol which could be put in a circuit diagram?
Yes, both a key switch and a reed switch have standard symbols that can be used in circuit diagrams. The symbol for a key switch is typically represented as a rectangle with a gap in the top portion, symbolizing the key inserted. The symbol for a reed switch is often depicted as a rectangle with two parallel lines inside to represent the reed contacts.
What is switch called that rotates with an electromagnet?
A rotary switch.
What does the switch do to the electro magnet?
The switch is turned on to activate the electromagnet, and metal is attracted. Turning off the switch stops the electromagnet from working, and metal is no longer attracted.
What is the function of the switch in the electromagnet crane?
The switch in the electromagnet crane controls the flow of electric current to the electromagnet. It allows the operator to turn the magnet on and off, enabling them to pick up and release loads.
What is a reed switch used for?
A reed switch uses two magnetized strips of metal to make or break a contact when a magnet is brought close to them. The door magnet near a reed switch on the door casing will cause the reed switch to close and moving the magnet away will cause the reed switch to open.
What is a reversing switch that rotates with an electromagnet?
Commutator

On a reed switch why are the strips made of iron and not steel?
because a reed switch is like an electromagnet so the purpose of it is that it will spring open when you remove the magnet. Iron is better because it looses it's magnetism quicker, whereas steel strips don't loose their magnetism as quickly so when you do remove the magnet, a steel strip would stay closed for a while longer rather than open straight away :D
How does electric bell using an electromagnet works?
When the bell switch is pressed, this completes the circuit. So, the electromagnet becomes magnetised and is attracted to an iron armature, which then hits the bell. Because the armature has moved it has broken the circuit so it moves back. When it moves back it completes the circuit again and so carries on ringing the bell like this until the switch is released.
How does metal corrosion affect a reed switch?
Metal corrosion can lead to the formation of insulating layers on the metal contacts of a reed switch, preventing proper electrical contact. This can result in unreliable switching behavior or complete failure of the reed switch. Regular maintenance and protection from corrosive environments can help prolong the lifespan of a reed switch.
Does a key or reed switch have a symbol which could be put in a circuit diagram?
Yes, both a key switch and a reed switch have standard symbols that can be used in circuit diagrams. The symbol for a key switch is typically represented as a rectangle with a gap in the top portion, symbolizing the key inserted. The symbol for a reed switch is often depicted as a rectangle with two parallel lines inside to represent the reed contacts.
How does a reed switch work?
Air pressure developed in the lungs blown into the mouth cavity and across the reed causes the reed to produce a mechanical resonance (it vibrates) at the natural resonant frequency of the reed. In the case of most reed instruments further tuning is achieved by changing the resonant cavity size of the instruments piping.
