Magnetic Strength vs. Voltage

CSEF · 2011 Electronics & Electromagnetics

Taran F. Lynn · Whale Gulch School, Whitethorn, Mendocino County

Overview

Objectives/Goals My objective is to determine the relationship between magnetic strength and voltage. Methods/Materials My materials included: 10 equal-sized magnets, a voltmeter, insulated copper wire with clip ends, and a plastic tube attached to a gallon water container. I set my experiment so that the plastic tube was wrapped with the copper wire which was connected to the voltmeter. I dropped the magnets through the tube and noted the voltage indicated. I put different numbers of magnets together to change the magnetic strength. Results As the number of magnets increased the voltage increased. Conclusions/Discussion As you increase the magnetic strength the voltage increases.

Summary statement

This project proves the direct relationship between magnetic strength and voltage induced.

Help received

Dad helped type, brother got magnets, and science teachers gave advice.
