Table 1: Varying Voltage Amount of Voltage (Volts) Number of Pins Attracted

This document describes an experiment to construct an electromagnet and determine factors that increase its magnetic force. Students will build an electromagnet by winding wire around a nail connected to batteries and measure its ability to attract paper pins under varying voltage and number of coils. They will then answer questions about how increasing voltage and coils affects the electromagnet's strength and explain its functioning in terms of electrical and magnetic concepts.

4.____________________________ 8.________________________

Objectives

 To be able to construct an electromagnet.


 Determine the factors the increase the magnetic force of an electromagnet.

Materials

 4 pcs. of (AA) 1.5 V battery


 Solid Breadboard Wire (at least half meter)
 15 pcs. of metal paper pins
 Nail (2 inches)

Procedure

1. Cut the end of the wire and peel off the plastic covering of the wire.
2. Once the cooper is exposed wind the wire in the nail’s body and create a coil/solenoid.
3. Connect the ends of the wire to the battery.
