Yes. That should work. Also, cupid's idea is equally good.helpme2011 said:

An electromagnet is a type of magnet that is created by passing an electric current through a coil of wire. The current produces a magnetic field that can be turned on and off by controlling the flow of electricity.
An electromagnet works by using the properties of electricity and magnetism. When an electric current flows through a wire, it creates a magnetic field around the wire. By wrapping the wire into a coil and increasing the number of turns, the magnetic field becomes stronger. This creates a temporary magnet that can be turned on and off by controlling the flow of electricity.
Electromagnets have many practical uses in our daily lives. They are used in electric motors, generators, speakers, doorbells, and many other devices. They are also used in industrial applications, such as cranes, magnetic levitation trains, and MRI machines in the medical field.
To investigate the strength of an electromagnet, you can use a variety of materials, such as nails, paperclips, or magnetic balls, and see how many of them the electromagnet can pick up. You can also vary the number of turns in the coil or the amount of current flowing through the wire to see how it affects the strength of the electromagnet.
When conducting an electromagnet investigation, it is important to follow basic safety precautions. Make sure to use insulated wires and keep the current at a safe level to avoid electric shocks. Also, be careful when handling strong magnets, as they can pinch the skin and cause injuries. Lastly, always have adult supervision when working with electricity.
