I have made a simple ir circuit that switches an LED on and off How can you replace the LED in the circuit with a homemade electromagnet so it can pick things up when triggered?

To create an electromagnet, you need to find a nail or similar long piece of ferrous metal. Then, take a wire and tightly wrap a wire around it as many times as you can in continuous coils.
All you have to do once you have made the electromagnet is connect the two ends of the wire into your previously created circuit.

Is a circuit breaker an electromagnet?
No.
What happens to the electromagnet when the circuit is closed?
An electromagnet if formed by pushing current through a coil. If the circuit is truly open, current will cease to flow, thus no electromagnet.
What is an advantage of using an electromagnet rather than a regular magnet?
A regular magnet, "Earth Magnet", can be very strong, the disadvantage of using them is that you cannot turn off the magnet. Electromagnet uses the electricity of a common battery and can be turned on and off, such as for switches in a circuit board.
How does a circuit breaker use an electromagnet?
The electromagnet in the circuit breaker is used for instantaneous tripping if short-circuit condition arises. At defined current level the electromagnet develops the force high enough to cause the tripping of the mechanism.
What is a relay instrument?
Relay is an electrically driven switch. It is an electromagnet to perform switching mechanically but other type of switches are also available. It is employed when a circuit is required to be controlled with a low input signal.
A safety device that uses an electromagnet to shut off the circuit is called a?
A safety device that uses an electromagnet to shut off the circuit is called a contactor.
What are the switches in the circuit used for?
To open and close the circuit.
What are the switches in the circuit use for?
To open and close the circuit.
How is an electromagnetic used in a doorbell circuit?
An electromagnet is an essential piece on a doorbel circuit. The electromagnet enables the operation of the a self-interrupting circuit. Special electromagnets called solenoids are used for doorbells with chimes.

Explain how an electric bell works?
When the bell is pressed the contact screw comes in contact with the iron strip and the circuit is complete . The current starts flowing through the coil. The electromagnet gets magnetised ant the soft iron armature gets attracted towards the electromagnet. The movement of the hammer causes the hammer to hit the gong. This movement beaks the circuit so that the current stops flowing and switches of the electromagnet. The spring pulls the armature back to it's original position , the circuit is remade and the process starts over again .This is how the bell rings.
