# MAGNETIC FORCE

BY CHARLOTTE AND FAITH

# Question

Does the size of the magnet affect the magetic force it has?

# Hypothesis

We think the Horse Shoe magnet has the most magnetic force because we think the bigger it is the more force it will have.

# Materials

~ Ruler

~ Paper Clip

~ Horse Shoe Magnet

~ Circle Magnet

# Steps

~ Get materials [ Paperclip,Ruler,Horse Shoe Magnet,Circle Magnet]

~ Lay a ruler out on the centimeters side [ 0 to 30]

~ Put the paper Clip at the end [side with the 0]

~ Place the circle magnet on the opposite side of the paper clip

~ Move the circle magnet to [5 centimeters]

~ Move the circle magnet to 3 centimeters if it dose not attract

~ Move to 2 centimeters if it dose not attract

~ Move to 1 centimeter if it doesn't attract

~ move to 5 millimeters slowly

~ Move to 4 millimeters slowly

~ The circle magnet was attracted at 4 millimeters

Do two more tests and write down then data

~ Write down the three tests in millimeters then write down the circle magnets average score

Pull the paper clip off the circle magnet and put it at 0 and the paper clip off to the side

~ Take the horse shoe magnet and put it at 5 centimeters = 50 millimeters

~ Move to 2 centimeters slowly

~ The horse shoe magnet was attract at 20 millimeters

~ Do two more tests in millimeters then write down the average of the three tests

~ Do a CER on what you discovered and why

# Data

Circle Magnet

Test 1   4 millimeters

Test 2  4 millimeters

Test 3   4 millimeters

Horse Shoe Magnet

Test 1   20 millimeters

Test 2   25 millimeters

Test 3    20 millimeters

# CER

We discovered that the bigger a magnet is the more force it will have. We found info by doing three trails for the circle magnet horse shoe magnet. Now we know the bigger the magnet the more force it will have.
