How To Make An Electromagnet With A Switch

Try adding more batteries to the circuit to make the electromagnet more powerful.

How to make an electromagnet with a switch. Get all the materials needed. Electronic switchdriver for lifting electromagnets. Add tip ask question comment download. If you wire a lightbulb into the circuit the electricity will power the bulb.

At its simplest an electrical circuit transfers electricity from the negative terminal of a battery through a wire to the positive terminal of the battery. A battery a light and a switch controlled by the electromagnet in circuit one. Open the switch and connect the wire from the other end of the nail to the terminal on the switch. The first circuit must create an electromagnet.

An electromagnet with a switch youll need 2 fasteners paperclip 2 foot piece of insulated wire 5 inch piece of insulated wire d cell battery electrical tape and nail i used a drill bit. A simple electromagnet consisting of a coil of insulated wire wrapped around an iron corethe strength of magnetic field generated is proportional to the amount of current through the winding. If the battery becomes hot that means it is working. Use electrical tape to connect the wires to each end of the battery.

Cut a short piece of wire and tape one end of it to the positive terminal of the battery. Hold the copper wire ends tightly to the top of the battery and move the metal bar or nail with the battery to the paper clips and you should be able to lift them. When this electromagnet is turned on it must close a switch in the second circuit turning it on and powering a light bulb. This will show you how to do a homemade onoff switch with stuff ou can find around the house from little to no cost to you.

This circuit diagram given below demonstrates the simplest form of an electromagnet driver. When it becomes necessary to switch or control a lifting electromagnet by an external device or microcontroller circuit you should need an appropriate circuitry based on a bjt or power mosfet. Electromagnet with a switch and battery. Now you have make your electromagnet d enjoy.

If youre using a larger piece of metal its only necessary to wrap the strand of metal with one layer of wire for. Wrap the wire tightly around the metal so that the electrical current conducts well.
