Name Date

Lab

Directions: In this lab, you will construct your own electromagnet and test how

strong that magnet is.

Materials

? a standard battery

? insulated copper wire

? large iron nail

? staples or paperclips

Instructions

1. The copper wire will act as solenoid, and the nail will act as the ferrous core.

Wrap the wire around the nail as many times as you feel you need to. Be

careful not the overlap the wire. Record the number of coils you wrapped

around the nail.

2. Once the solenoid is wrapped around the core, connect the ends of the wire

to the ends of the battery. This will send an electric current through the wire

and immediately magnetize the nail. The nail will now act as an

electromagnet.

Record the distance of how far away the staples or paperclips have to be in order to start being attracted to the electromagnet. If the distance is too small to record, simply record that as “contact distance.” 4. Repeat the experiment two more times with different amounts of coils around the electromagnet. 5. Be aware of heat buildup. Using too many batteries, batteries that are too high voltage, or using too many coils can result in high heat buildup. Please be cautious when doing this lab. Data Analysis Create a data table of the number of coils and the distance at which the magnetic field affected the test objects. Trial Number of Coils Distance from which object was attracted to electromagnet 1 2 3 4 5 6 Answer the following questions: 1. Did the number of coils have an effect on the overall strength of the electromagnet you created? 2. What are some other ways you think you could increase/decrease the strength of an electromagnet? © 2018 Pearson Online & Blended Learning K–12 USA. All rights reserved. 2 3.
