Electrons behave like little magnets and when they flow through a wire, they create a magnetic field, which turns the nail into a magnet that can pick up paper clips and staples!

To make it a true experiment, you can try to answer these questions: 1. Does the number of times you wrap the wire around the nail affect the strength of the nail? 2. Does the thickness or length of the nail affect the electromagnets strength? 3. Does the thickness of the wire affect the power of the electromagnet? Science Bob.

Make an electromagnet out of a few simple supplies. This is a great way to explore not only electrical circuits, but also the connection between electricity and magnetism. In this experiment, kids will take an ordinary nail and make it magnetic. This is a …

A cool science experiment which teaches kids about a magnetic field is to make an electromagnet from scratch. Electromagnet principles and theory was developed by Andre Marie Ampere in 1821. D.F. Arago then invented the first working electromagnet. This invention helped lead Michael Faraday to later invent the electric motor. Materials Needed

How to Make a Magnet with a Battery Wire and Nail If you are looking for a fun and slightly dangerous science experiment for your class or homeschool, you've come to the right place! Depending on how you attempt to make a battery magnet with a wire and a nail, this solenoid science project for kids can be a lot of fun or go very wrong. Perfect ...

With this electromagnet, the days when you picked up paper clips with your bare hands are finally over. This is an experiment about how an electric cable can become a magnet. Warning! Disconnect the battery when not in use, otherwise the cable may become hot and cause a fire. Strip off 5-10 mm (1/4-1/2 in) of insulation at both ends of the wire.

2021年4月12日 · In this experiment, we will create an electromagnet by wrapping a copper wire around a metal piece such as an iron nail. The copper coil is then attached to an electrical source such as a battery. When the electricity flows from the battery through the copper wire – the circuit produces a magnetic field around the coil – which magnetizes ...

When an electric current passes through the wire, it creates a magnetic field in the metal core (the nail). When the wire is wrapped around the iron nail and the battery is strong enough, you create a simple electromechanical solenoid.

Conduct this simple electromagnetic induction experiment to witness this phenomenon for yourself! Observe how current can create a magnetic field. What will happen when the battery is connected and the switch is turned on? Will the battery …
